SUMMARY
Site Name: Cadnam Farm,
Location: Alton, Hampshire
NGR: SU 72025 41075 Type: Excavation
Date: January-February, 2016
Planning Reference: 55488/001
Location of archive: Hampshire Cultural Trust, Accession Number: A2015.66
Site Code: CADF 16
A programme of archaeological excavation was undertaken by Cotswold Archaeology in
January and February, 2016, at the request of Persimmon Homes (South Coast), and Martin
Grant Homes (the clients), at the Cadnam Farm site. Three individual areas, totalling 0.55ha,
were excavated across the proposed development area.
Area 1, within the north-east of the Site, contained a D-shaped enclosure of Middle Iron Age
date, which contained the remains of a roundhouse, and was associated, on its north-west
side, with a ditched drove-way. A number of associated features included refuse pits, a four-
post structure and a small post-built structure of circular plan. Pit 10041 in Area 1 produced
a mixed assemblage of finds, including bone weaving combs, pottery and items of
metalwork, all from a fill, 10043, which has been interpreted as a structured deposit.
Area 2 was situated on the north-east margins of the site, and contained the superimposed
foundation gullies of two roundhouses, with a probable third example situated slightly to the
south-west. The roundhouses contained internal, concentric post settings, and were of
Middle Iron Age date. Area 3 was located close to the north-west boundary of the Site, and
contained the remains of a circular-plan, post-built structure in its north-east corner, with an
adjacent four-post structure and associated post holes and pits, most of which were
undated. A number of paired and single post holes, together with a six-post structure, were
located within the north-west corner of Area 3, and a discrete cluster of post holes, further to
the south-east, represented a further small structure of indeterminate plan. A number of
these features were assigned a Middle Iron Age date on the basis of pottery. Two large
boundary ditches extended into Area 3, from its south-west corner, and were interpreted as
the funnelled entrance of a drove-way. A number of internal post settings may represent
structures associated with livestock handling. Two phases of ditches were evident, but these
were principally of late Iron Age/Early Roman date. An article summarising the results of this
excavation, will be published in a future volume of the Hampshire county journal.

1. INTRODUCTION 1.1 During January and February, 2016, Cotswold Archaeology (CA) carried out an
archaeological excavation at the Cadnam Farm site, centred on NGR: SU 72025
41075 (Fig. 1). The work was undertaken at the request of Persimmon Homes
(South Coast), and Martin Grant Homes, in accordance with a brief for
archaeological investigation and recording prepared by Neil Adam, Senior
Archaeologist, Hampshire County Council, the archaeological advisors to the Local
Planning Authority (LPA), and with a subsequent, detailed WSI produced by CA
(2016), and approved by the LPA acting on the advice of the curator. The fieldwork
also followed Standard and Guidance for Archaeological Excavation (CIfA 2014),
the Management of Research Projects in the Historic Environment (MORPHE):
Project Manager’s Guide (Historic England 2015a), and accompanying PPN3:
Archaeological Excavation (Historic England 2015b). It was monitored by the
curator, including site visits made on February 4 and 6, 2016.
1.2 This report presents the results and assessment of the evidence recovered from the
excavation, including stratigraphy, finds and biofactual evidence. It considers the
evidence collectively, in its local, regional and national context, and provides the
basis for a publication article.
The site
1.3 The development Site is c.12.6ha in extent, and is bordered to the south by an area
of modern residential development on the north-eastern margins of Alton (Fig. 1).
The Site extends across four agricultural fields (Fields 1 – 4, Fig. 2), with the
buildings of Cadnam Farm situated outside the Site, to the north, and those of
Blanes Farm situated within the Site, and just to the north-west of its southern
boundary (Fig. 2). The Site is bounded by open agricultural fields to the north, and
west and by a footpath and further fields to the east. It is divided into two
approximate halves by Upper Anstey Lane, which runs, on a south-east/north-west
alignment, through the centre of the Site. To the south, the Site is bordered by
Gilbert White Way and associated residential developments.
1.4 The Site is dominated by an area of higher downland to the north and west, and
overlooks the valley of the River Wey, which runs c. 1km to the south-east. The Site
lies on a gentle, north-south gradient, extending from an elevation of 146m above
![Page 8: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/8.jpg)

corner of Field 1.
1.5 The British Geological Survey Mapping (BGS 2015, online), and the results of an
archaeological evaluation (CA 2015), indicate that much of the Site is underlain by
New Pit Chalk of the Cretaceous period, with the northern parts of the Site underlain
by Lewes Nodular Chalk, or by superficial deposits of Clay-with-Flints.
Planning Context
1.6 Outline conditional planning permission (Ref: 55428/001) has been granted by East
Hampshire District Council (EHDC; the local planning authority [LPA]), for the
construction of up to 275 residential dwellings, together with associated landscaping,
a children’s play area, open space, and associated infrastructure, car parking and
roads.
1.7 Following consultation with Neil Adam, Senior Archaeologist at Hampshire County
Council, the archaeological advisor to East Hampshire District Council, an
evaluation was undertaken in October and November 2015, by Cotswold
Archaeology (CA 2015). This comprised the excavation of 86 no. 30m x 2m trial
trenches, which represented a 4% sample by area of the 12.6ha Site. The
evaluation followed, and was informed by, an earlier desk-based heritage
assessment (WSP 2014) and a geophysical survey (PCG 2015).
1.8 The evaluation identified two areas of dispersed Iron Age settlement activity within
the north-eastern and central parts of the Site. A summary of the results of
evaluation is presented in Section 2 of this report.
2. ARCHAEOLOGICAL BACKGROUND
Introduction 2.1 The Cadnam Farm site was the subject of an earlier desk-based assessment (WSP
2014), which was undertaken to support an application for outline planning
permission (Ref: 55428/001). The assessment encompassed a 1km-radius Study
Area around the Site, to enable it to be considered within its local archaeological and
historical context. These results, including those of a geophysical survey (PCG
2015), which were used to inform subsequent evaluation and excavation strategies,
![Page 9: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/9.jpg)

are included within the assessment of archaeological background for the Site, which
is presented below.
Earlier Prehistoric Periods (c. 10,000 BC to c. 700 BC) 2.2 There are no known heritage assets of earlier Prehistoric date recorded within the
Site. There are, however, a number of recorded finds of prehistoric date within the
surrounding study area, including a Palaeolithic hand axe (500,000 - 10,000 BC,)
and possible Neolithic worked flakes (4000 – 2400 BC) recorded within the Parish of
Alton. Bronze Age finds (c.2400 – 700 BC) have also been recovered from within the
Study Area, and the Hampshire Historic Environment Record (AHBR) records
evidence of later Bronze Age (1100-700 BC), and possibly Early Iron Age (700-400
BC), activity within the environs of Treloar College, c.700m to the east of the Site.
Iron Age (c. 700BC – AD 43) 2.3 The Cadnam Farm site is situated within an area which has hitherto been associated
with only limited evidence of Iron Age or earlier prehistoric settlement, and only a
small number of recorded sites offer a degree of regional context. Of relatively
recent finds, the Alton Hoard, of first-century AD Atrebatic gold staters and items of
jewellery, was discovered in 1996, within the vicinity of the town. Recorded
settlement sites of Iron Age date within the wider environs of the Site are relatively
few, but include St John’s Hill, East Worldham (Scheduled Monument 1020314),
which is situated 4.8km to the south-east of Cadnam Farm, and comprises a small
univallate enclosure of Middle and Late Iron Age date. The cropmark of a large, D-
shaped enclosure of Middle and Late Iron Age date has been recorded to the east of
Dickett’s Plantation, Froyle (SU 7232 4345, Fig. 1) (Millett 1981, 49-53), at a location
2.4km to the north-north-east of Cadnam Farm. This has been suggested (ibid.) as a
possible Late Iron Age elite settlement, which may have functioned as a precursor of
the Roman ‘small town’ at Neatham (Fig. 1). Millett’s small-scale investigation (ibid.)
suggested that the enclosure ditches had been recut at the end of the Iron Age.
Beyond this example, a number of possibly-contemporary enclosed settlements are
located to the north-west of the Site. An earthwork enclosure with associated hollow-
way, is located within Humbly Grove, Weston Patrick (Monument number 243847,
SU 7032 4595), at a distance of 4.9km from Cadnam Farm, and a sub-rectangular
cropmark enclosure is located at Little Wood, Weston Patrick, at a distance of
7.3km. A further earthwork enclosure of probable Iron Age date is known at Weston
Common (SU 6944 4460), some 4km to the north-west, and Iron Age pits and
evidence of occupation have been recorded within the town of Alton. A possibly
![Page 10: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/10.jpg)

contemporary Late Iron Age burial has been recorded at Manor Farm, Alton, c. 1km
to the east of the Site. The cropmark evidence of a late prehistoric or Roman-period
field system around Manor Farm, Alton (monument no. 244121), may provide further
context for this period.
Roman (AD 43 - 420) 2.4 No finds or archaeological features of Roman date have been recorded within the
Site, although several Roman-period features and findspots have been recorded
within the area surrounding Treloar College and Manor Farm, respectively located c.
0.75km and 1km to the east. Antiquarian records of finds from this area include
coins, pottery, a lamp and a paved floor. Excavations in the 1980s, at Manor Farm
Cottages, Neatham, c. 1.74km to the east of the Site, revealed evidence of Roman-
period occupation of the second to fourth centuries AD, possibly associated with
contemporary ‘ribbon development’ along the Silchester-Chichester Roman Road
(Graham 1990, 17-30).
2.5 The site of a Roman ‘small town’ is located 1km to the south-east of the Site, near
Neatham, which is located at a significant junction of Roman roads (Millett and
Graham 1986, 2-3) (Fig. 1). This site may be identified with that of Vindomis, a
Roman town which is mentioned in the Antonine Itinerary of the 3rd century AD, and
which apparently lay on the road between Silchester (Calleva Atrebatum) and
Chichester (Noviomagus) (Rivet and Smith 1979, 82; Clarke 1959, 83-97). Roman
material has been recovered close to the medieval Manor House at Neatham,
including evidence of ironworking. Evidence of occupation of this date has also been
recorded in a number of areas within the town of Alton, notably at the southern end
of the High Street, and within the public gardens.
2.6 The earliest occupation within the Roman small town appears to date from the
Flavian period of the later first century AD (Millett and Graham 1986, 11, Table 1),
which is likely to post-date Period 3 on the Cadnam Farm site. However, the
excavations undertaken on the course of the Alton By-Pass in 1969-70, c. 130m to
the to the east of the small town site, recorded a small, Early Roman group of rich
cremation burials, together with two inhumation burials (Fig. 1). Of the cremation
burials, at least two (Burials 1 and 2) appear to date from AD 50-75, and thus
appear to demonstrate the presence of an elite social group in the area during a
period which is likely to have pre-dated the establishment of the ‘small town’, and
![Page 11: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/11.jpg)

which may therefore be contemporary with Period 3 of this Site (Millett and Graham
1986, 61; Millett 1986, 43-87).
Anglo-Saxon (AD 410 – 1066)
2.7 There are no known archaeological remains of Saxon date within the Site. Alton is
thought to have origins in the Saxon period, with the town name apparently
originating from the Old English Aewielltun, which may be roughly translated as ‘the
farmstead near the spring’ (Hopkins 2004). A large Early Saxon cemetery of the 5th
or 6th century, has been recorded within the Mount Pleasant area of the town, and
was associated with approximately 50 inhumations and a similar number of
cremation burials. The Alton Buckle, regarded as one of the finest pieces of
contemporary jewellery beyond the major contemporary Royal burial site of Sutton
Hoo, Suffolk, was recovered from Grave 16 in this cemetery, which was excavated
in 1959-61 (Evison 1988, 75-76). The will of King Alfred included a bequest of land
at Awielltun, although it is possible that this reference may actually relate to Alton
Priors in Wiltshire (Sawyer, 1968).
Medieval (1066 – 1539)
2.8 There are no known remains or findspots of medieval date within the Site boundary.
Within the wider environs of the Site, contemporary records relate to the
neighbouring village settlements of Holybourne and Ansty, and the surviving
earthworks of a former churchyard boundary. In 1070, King William is recorded as
having given an estate at Alton to the Abbey of Saint Peter (i.e. Hyde Abbey in
Winchester) (Sawyer 1968).
2.9 A royal estate at Alton is listed in the Domesday Survey as Neatham, and was
sufficiently large at that time to accommodate 52 ploughs, 96 people, eight mills and
a market (Munby 1982). Holybourne and Anstey were also recorded as royal
manors at this time. There has also been a suggestion that a pre-conquest Minster
Church stood in close proximity to the Roman road crossroads at Neatham (Hase
1994).
2.10 The presence of a market in Alton during the 11th century is attested in a Domesday
entry that describes Aoltone in Odingeton as a valuable market. The two Manors of
Alton Eastbrook and Alton Westbrook are recorded as each controlling a fair by the
thirteenth century. A Saturday market of some considerable size was operating in
![Page 12: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/12.jpg)

Alton by 1288, well in advance of the Charter of 1307 from Edward II, which
conferred on Alton the right to hold an annual fair.
Post-medieval (1540 – 1800) 2.11 During the Civil War, Alton was occupied by a detachment of the Royalist army,
under the command of Sir Ralph Hopton, but, in 1643 the town was taken by
Parliamentarian forces under Sir William Waller. In this action, Colonel Bowles was
killed at the Church door, and his regiment taken as prisoners. Waller’s forces,
numbering some 5,000, advanced along the Basing Road, before turning south
towards Alton, thus avoiding sentries posted to watch the main roads (Hopkins
2004).
2.12 A number of breweries were established in Alton during the post-medieval period,
together with paper-making, tanning and cloth-making industries, all of which had
become established by the 18th century. Timber and saw-mills were in operation
from at least the 1890s. There are no known archaeological remains of post-
medieval date recorded within the site. The surrounding study area also contains a
number of disused chalk pits, some of which are depicted on Ordnance Survey (OS)
maps, particularly on the higher ground to the west and north of the Site, and appear
to be associated with eighteenth and nineteenth-century land improvements. On
recent (2006) OS mapping, a field to the south of Field 4 is labelled as ‘Marlfield’,
suggesting that many of these disused chalk pits were quarried for the marling of
acidic soils on local farmland.
Geophysical Survey
2.13 A geophysical survey of most of the Cadnam Farm site was undertaken in
September, 2015 (PCG 2015), although Field 2 could not be surveyed, due to the
presence of a dense crop at that time. With the exception of Enclosure 1.1, whose
ditches were readily apparent, no other clear geophysical anomalies were identified
within the areas surveyed.
2.14 Within the north-east of Field 1, geophysical survey identified a D-shaped enclosure
of probable prehistoric origin (Enclosure 1.1), with a possible entrance at its south-
western corner. Evaluation trenches 73 – 77 were targeted on this feature, and
were amongst the very few trenches that were directly targeted on geophysical
anomalies. In addition, an east/west-aligned weak linear anomaly was recorded in
the centre of Field 1, which was thought to be of recent agricultural origin. Trench 59
![Page 13: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/13.jpg)

evaluated this anomaly, although no archaeological features were observed within it.
No other significant geophysical anomalies of possible archaeological significance
were recorded by the survey (PCG 2015).
Evaluation (Fig.2) 2.15 An archaeological evaluation was undertaken by Cotswold Archaeology in October
and November, 2015 (CA 2015). Eighty-six evaluation trenches were excavated,
representing a 4% sample (by area) of the proposed development area (Fig. 2). A
small number of the trenches (Trenches 73 to 77) were targeted on the geophysical
anomalies identified by an earlier geophysical survey (PCG 2015), including the
ditched enclosure in the north-east of Field 1. The evaluation recorded two areas of
dispersed Iron Age settlement activity within the north-east and north of Fields 1 and
2 respectively.
2.16 In Field 1, the evaluation confirmed the presence of a small, D-shaped, ditched
enclosure of Middle Iron Age date (Trenches 73 to 77), which had been identified by
the geophysical survey. In addition, what appeared to be a small, sub-oval enclosure
of possible Middle Iron Age date was identified in the north-east of Field 1 (Trench
84), although this was not apparent in the geophysical survey. Archaeological
features, including a small number of pits, postholes and ditches, were also
recorded to the north and east of the main enclosure (Fig. 2). While a number of
features produced no dateable material, a small assemblage of Middle Iron Age/Iron
Age pottery, worked and burnt flint, animal bone, fired clay fragments, a worked
bone textile comb and a copper alloy pin, were recorded, most particularly from the
fill of a large post pit (7907) in Trench 79. These finds, along with spatial
associations between identified features, suggested that most of the evaluated
features were broadly contemporary.
2.17 Significant finds were principally associated with two large post pits (7903, 7907),
which were situated at the eastern end of Trench 79, to the north-east of Area 1
(Fig. 2). Both pits were near-vertically sided, with flat bases, and measured c.0.8m in
maximum diameter by 0.15 – 0.25m in depth. The basal fill, 7904, of post-pit 7903,
contained common, large flints, animal bone, fired clay fragments and a Middle/Late
Iron Age bone comb (Evaluation Ra. 1). It also displayed a clear post-pipe of 0.27m
diameter, of which the fill, 7906, contained a chalky deposit (7905), with relatively
common charcoal, but no finds. The single fill 7908 of post pit 7907, contained a
near-complete, Middle Iron Age pottery vessel (Evaluation Ra. 2), in addition to
![Page 14: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/14.jpg)

animal bone (pig) and relatively common charcoal inclusions. It is possible that both
the pottery vessel and the bone comb represent specially-placed items, and these
are discussed further in Section 8, below.
2.18 Another area of features of mostly Late Iron Age date was recorded in the north of
Field 2, within Trenches 14, 16, 25, 26. These also comprised a small number of
ditches, pits and postholes (Fig. 2). These features contained assemblages of finds
similar to those associated with the features in Field 1, but did also include a very
small assemblage of residual Early Iron Age pottery. The Field 2 area of features
included two, sub-circular post-built structures which, although undated, possibly
represent small stock pens, or windbreaks, of Middle or Late Iron Age date. It also
included a single four-post ‘granary’ structure.
2.19 In addition to two post-medieval chalk pits, which were located in the east of both
Fields 1 and 2, a large, undated field boundary ditch was recorded, which ran along
the east side of Field 1, running parallel with, and possibly representing a precursor
to, the present field boundary located immediately to the east.
3. AIMS AND OBJECTIVES
3.1 The aims of the excavation were to establish the character, quality, date,
significance and extent of any archaeological remains or deposits surviving within
the site. This information will assist the Local Planning Authority in making an
informed judgement on the likely impact upon the archaeological resource by the
proposed development.
3.2 The objectives of the archaeological excavation were to:
• record the nature of the main stratigraphic units encountered;
• assess the overall presence, survival and significance of structural and
occupational remains;
• assess the overall presence, survival, condition, and potential of artefactual
and ecofactual remains; and
• to gain a better understanding, and to clarify the nature, date and chronology
of, the archaeological features identified during the geophysical survey and
archaeological evaluation.

3.3 The specific aims of the excavation were to:
• record any further evidence of prehistoric evidence that may relate to past
settlement, funerary activity, industrial activity or other land use;
• to define the nature of the evidence for Middle Iron Age and Late Iron Age
activity identified during the evaluation;
• to characterise the enclosure identified in Trenches 73 to 77, and assess
evidence of settlement activity;
• to establish and define whether the Late Iron Age evidence identified in
Trenches 14, 16, 25 and 26 is indicative of domestic occupation, or whether
some other form of activity can be identified;
• recover artefact evidence to further refine the dating of past settlement that
was identified during the evaluation;
• sample and analyse environmental remains to create a better understanding
of past land-use and economy; and
• to date and characterise the large, undated field boundary ditch,.
4. METHODOLOGY
4.1 Three areas of archaeological strip, map and record excavation (Areas 1-3) were
identified on the basis of earlier geophysical survey and evaluation trenching (Fig. 2).
These were focused on the principal areas of archaeological interest identified by the
trial trench evaluation (CA 2015).
Area 1
4.2 This area measured approximately 45m x 55m (0.25ha), and was focused on the
small Middle Iron Age D-shaped enclosure identified by the geophysical survey and
by evaluation trenches 73 to 77. Area 1 was also intended to investigate the
relationship of the D-shaped enclosure ditch to a north/south-aligned ditch identified
in Trench 80 (Ditch 101).
Area 2
4.3 This area measured approximately 25m by 20m (0.05ha), and was focused on a
small, sub-circular feature identified within Trench 84. Investigation within this area
also sought to further identify, and date, a large, undated field boundary ditch, which
![Page 16: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/16.jpg)

was identified in trenches 70, 71, 72 and 85 (Fig. 2), which was thought to represent
a possible precursor to the present field boundary, immediately to the east.
Area 3
4.4 This area measured approximately 50m by 50m (0.25ha), and was focused on the
evidence from Trenches 14, 16, 25 and 26, which identified a small number of Middle
and Late Iron Age features, including ditches, pits and postholes, which were thought
to possibly indicate evidence of settlement.
4.5 Excavation areas were set out on OS National Grid (NGR) co-ordinates, using a
Leica GPS, and scanned for live services by trained staff using CAT and Genny
equipment, in accordance with the Cotswold Archaeology Safe System of Work for
avoiding underground services. Allowance was made for the possible adjustment of
the position and size of excavation areas to account for the presence of services and
other constraints, with the approval of the HCCPA. The final ‘as dug’ areas were
recorded with GPS. Provision was included within the Written Scheme of
Investigation for excavation areas to be extended if significant archaeological
remains were observed to extend beyond their initial limits.
4.6 Excavation work initially comprised the mechanical removal of archaeologically non-
significant soils, under constant archaeological supervision, using a toothless ditching
bucket. The generated spoil was monitored in order to recover artefacts. The hand-
cleaning of stripped surfaces, to better define any identified archaeological
deposits/features, was undertaken where necessary. All machining was conducted
under archaeological supervision, and ceased when the first archaeological horizon
or natural substrate was revealed, whichever was encountered first. All
archaeological features were recorded in plan, using Leica GPS.
4.7 During the course of the stripping, all potential archaeological features and spoil
removed was scanned by a metal detector to ensure that any significant features or
material were identified/collected at an early stage of the fieldworks.
4.8 The archaeological features thus exposed were hand-excavated to the bottom of
archaeological stratigraphy. All features were planned and recorded in accordance
with CA Technical Manual 1: Fieldwork Recording Manual (CA 2013). Deposits were
assessed for their environmental potential in accordance with CA Technical Manual
2: The taking and processing of environmental and other samples from
archaeological sites (CA 2012). All artefacts recovered from the excavation were
![Page 17: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/17.jpg)

retained in accordance with CA Technical Manual 3: Treatment of finds immediately
after excavation (CA 1995).
4.9 The examination and recording of features concentrated on recovering plans and any
structural sequences. Particular emphasis was placed on retrieving a stratigraphic
sequence, and on obtaining evidence for the phasing of the site. Provision was made in
the Written Scheme of Investigation for all evidence of funerary or ritual activity, and
domestic/industrial deposits, to be fully excavated. All discrete features (including post
holes and pits) were sampled by hand excavation (average sample unlikely to exceed
50%) unless their common or repetitious nature suggested that they were unlikely to
yield significant new information. All linear features (ditches, pathways etc) were
sampled to a maximum of 10%. Priority was given to those features which contained
sealed assemblages which could be related to the chronological sequence of the site. In
the case of deep features, hand-excavation ceased at a maximum depth of 1.2m in the
first instance, and feature edges were stepped or shored, as appropriate.
4.10 A full photographic record of the excavation was kept. The primary photographic
record was captured on Canon digital SLR equipment. The record included detailed
images of archaeological deposits and features, to illustrate their location and
context, together with the location and context of the separate working areas of the
site. The record included images of the site overall, and working shots which
illustrated the general progress of archaeological investigation.
4.11 All artefacts were recovered and retained for processing and analysis, in accordance
with the CA Technical Manual 3 Treatment of Finds Immediately after Excavation.
Material of undoubtedly modern date was not noted or retained. All artefacts were, as
a minimum, washed, weighed, counted and identified. Any artefacts requiring
conservation, or specific storage conditions, were dealt with immediately, in
accordance with the guidance document First Aid for Finds (Leigh, Watkinson and
Neal 1998).
4.12 Due care was taken to identify any deposits which were considered to have
environmental potential, and while provision for a programme of environmental
sampling was detailed within the Written Scheme of Investigation, the general
character of deposits and levels of preservation on the Cadnam Farm site limited the
scope for environmental sampling, and only seven bulk samples were recovered
across the site as a whole.

5. RESULTS: FIELDWORK SUMMARY
5.1 This section provides an overview of the results of excavation, including detailed
summaries of recorded contexts. Detailed descriptions of finds and environmental
samples (biological evidence) are to be found in Sections 6 and 7 of this report, and
are summarised in Appendices B to F. Following the completion of fieldwork, an
ordered, indexed, and internally consistent site archive was compiled in accordance
with specifications presented in the Management of Research Projects in the Historic
Environment (MORPHE), and the Project Manager’s Guide (Historic England 2015a).
A database of all contextual and artefactual evidence, and a site matrix, was also
compiled, and cross-referenced to spot-dating.
5.2 The survival and intelligibility of the site stratigraphy was limited, with archaeological
remains partly surviving as negative features, but frequently truncated by later
cultivation. In a number of cases, most notably in the cases of Roundhouses 3 and 4
(Fig. 4), it was possible to interpolate the course of missing sections of ring-gulley to
establish a basic plan. Despite a relative paucity of stratigraphic relationships, most
principal features have been assigned a preliminary period on the basis of context
dates and/or spatial associations.
5.3 The excavations revealed evidence for Middle and Late Iron Age/Early Roman
agricultural and domestic activity across the Site. In Area 1, the enclosure identified
by geophysical survey and evaluation was revealed as a Middle Iron Age ‘D’-shaped
enclosure, which contained the remains of a roundhouse. To the north-east of the
enclosure were six pits, one four-post structure, one small, post-built structure, and
two parallel ditches comprising an associated drove-way, were also recorded. Area 2
was located c. 50m to the north-east of Area 1, above a hill-slope. It contained one,
relatively complete ring-gulley, and five segments of curvilinear gullies, which
collectively appear to represent the remains of three individual roundhouses
(Roundhouses 3-5, Fig. 4). In addition, Area 2 contained 13 associated post holes,
three segmented gullies, and four small pits, most of which appear to represent
internal, concentric post settings within respective roundhouses. In the western end
of the site, in Area 3, located c. 175m to the south-west of Area 1, the entrance to
what appeared to be a large Late Iron Age or Early Roman drove-way, marked by
large ditches of sub-rectangular plan, was identified. These ditches appeared to
extend beyond the south-east edge of Area 3, on a north-east/south-west alignment.
![Page 19: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/19.jpg)

Area 3 also revealed 47 individual post holes and five pits, of which the post holes
defined at least one four-post, and one six-post structure, together with a further
small, post-built roundhouse and a structure of indeterminate plan (Fig. 5).
Phasing
5.4 The assigning of features to periods was principally based on the dating of artefactual
evidence, although many features produced no dateable material. Where possible,
these have been broadly dated on the basis of spatial relationships with, or similarity
to, dateable deposits. On the basis of these criteria, recorded finds and features
were assigned to the following provisional periods:-
• Period 1: Mesolithic to Bronze Age (c.10,000 - 700 BC) (Residual worked flint)
• Period 2: Middle to Late Iron Age (c.400 BC to 50 BC)
• Period 3: Late Iron Age to Early Roman (c.50BC – AD 75)
• Undated
5.5 Period 1 is represented only by a single item of worked flint from Area 3, which can
be only broadly dated to the Prehistoric period. There was otherwise some
chronological distinction evident between different parts of the Site, with Period 3
features almost entirely confined to Area 3 (in the western part of the site), and
Period 2 features largely confined to Areas 1 and 2 (in the eastern part of the site).
Period 2 was largely defined by the presence of hand-made Middle Iron Age pottery
typologies, and was the only period represented in Area 2.
5.6 The Period 2 features evident within all excavated areas suggest a newly-established
settlement of Middle Iron Age date, with little evidence of earlier Prehistoric activity,
although small quantities of residual Early Iron Age pottery was recorded from pits
and ditches within Trenches 14, 16, 25 and 26 of the evaluation. The relatively long
currency and lack of stylistic differentiation of regional Middle Iron Age pottery
typologies permits very little refinement of phasing within this period. While there is
some evident inter-cutting of Period 2 features, there is little possibility of placing
these within any broader Period 2 sequence across the site. Thus, while all
excavated areas contained Period 2 features, it is not possible to demonstrate the
extent to which these were contemporary, or to identify any diachronic patterns of
Period 2 change across the site as a whole. However, the well-attested character of
Middle Iron Age settlement elsewhere across the Hampshire chalklands, including
![Page 20: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/20.jpg)

Easton Lane (Fasham et. al 1989, 58-7-, Fig. 72) and Winnall Down (Fasham 1985,
18-26), makes it possible to suggest that the Period 2 features across the Cadnam
Farm site, and by implication many undated features, relate to a single, coherent
phase of settlement by a small social group during Period 2, which may have been of
fairly limited duration. On this basis, it is probable that house remains, and possibly
contemporary associated structures across the site, are of broadly contemporary
date.
5.7 The fill of gulley 106, which extended from Ditch 103 of Enclosure 1.1, was
associated with pottery of Late Iron Age type, and has thus been tentatively assigned
to Period 3 (Fig. 3). However, this appears to represent the latest dateable feature
within Area 1, which thus presumably demonstrates continuity with the Period 2
features which otherwise characterise this Area. This may indicate that Enclosure
1.1, and possibly other Phase 2 features across the site, date from the later part of
the Middle Iron Age Period 2 which, on a purely ceramic basis (Brown 1984, inter
alia), could theoretically date these features as late as the earlier first century BC.
This conforms to McSloy’s opinion (this report) that the pottery evidence supports a
distinctly later Middle Iron Age date for Period 2, and thus one which suggests
possible continuity with Period 3 in Area 3.
5.8 Throughout this report, clear distinctions have been made between dateable and
non-dateable features (Figs. 3-5), except in those few cases where contextual or
spatial associations permitted a confident assignment of date. Thus Roundhouse 2 in
Area 1 and Roundhouse 6 in Area 3, together with a number of pits and four and six-
post structures, remain technically undated, although on the basis of form and
comparative dated examples elsewhere, these are most probably of Period 2 date.
With the possible exception of Ditch 103 and gulley 106, no Period 2 features also
contained Period 3 material, and it is therefore reasonable to assume that occupation
within the areas excavated was abandoned at some time towards the end of the
Middle Iron Age, to be partly replaced by the layout of ditched boundary features
forming the putative drove-way entrance in Area 3. However, the Period 3 ditches
contained industrial debris and domestic material of this date in their fills, suggesting
that contemporary occupation and activity may have occurred nearby. It is possible
that these Period 3 ditches, 301 and 302, were continuous with other features across
the Site, although no evidence of these was identified by evaluation or within the
immediate environs of Area 3 (Fig. 2).
Geology and soil sequence

5.9 The natural substrate across the majority of the Site was underlain by New Pit
Chalk, with northern parts of the Site underlain by Lewes Nodular Chalk, or by
superficial deposits of clay-with-flints. Patches of light, greyish-brown silty clay,
representing degraded chalk, were observed in Area 3. Both chalk and clay-with-
flints substrates were recorded at depths of 0.3 – 0.7m below modern ground level.
However, in places, a c. 0.3m-thick colluvial deposit of light to dark reddish-brown
clayey silt was recorded, which increased in depth further downslope, and which, on
the north-western margins (Trench 14), was cut by archaeological features of Period
3 date.
5.10 Where colluvium was present, the natural chalk or clay-with-flints geology was
recorded at a depth of c. 0.7m within the lower parts of the Site. The natural chalk
was of fairly good quality, with very common flint inclusions. It was commonly
lightly-weathered and fractured, and with very few solution channels and hollows of
periglacial origin, although one large solution channel was recorded in evaluation
trenches 78, 79 and 82. The clay-with-flints geology comprised mid-red/brown silty
clay, with common angular and sub-angular flint inclusions. This was encountered
across almost the whole Site, except for within the eastern part of Field 1, and the
north of Field 2.
5.11 At the margins between these two component natural geologies of the site, a light
brown clay/silty clay, with moderate to common chalk and flint inclusions, was
recorded, which appeared to comprise a periglacially or geochemically-weathered
interface between the natural chalk and the clay-with-flints deposits.
5.12 Periglacial channels cutting the chalk geology were recorded in a number of
locations, particularly in the north of Field 2 (Area 3). However, between Areas 1
and 2, a large, slightly curving, NNW/SSE-aligned solution channel was recorded.
This was clearly indicated on the geophysical survey greyscale plot (PCG 2015,
Fig. 2) and was subsequently identified by evaluation (Trenches 78, 79 and 82), as
a feature c.3-4m wide and c.0.52m deep, and filled with a homogenous and
archaeologically sterile red-brown sandy silt (Fig. 2, geological feature).
![Page 22: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/22.jpg)

Area 1 (Figs. 3, 6 and 7) Period 2: Middle to Late Iron Age (c. 400BC to AD 25) Ditches 101 and 102
5.13 Parallel ditches 101 and 102 extended beyond the northern edge of Area 1, on a
north-west/south-east alignment, and were separated by a distance of 8m. Ditch
101 (sections 10048 and 10076) ran for 23m before terminating, and measured an
average of 0.75m in width and 0.51m in depth, with a V-shaped profile. Section
10048 displayed three fills, of which primary fill 10049 was a thin, yellow-brown silty
clay layer derived from the weathering of ditch sides (Fig. 7). Secondary fill 10050
was a mid/light-grey/brown silty clay with a slightly humic character, which may
reflect the proximity of domestic occupation. The upper secondary fill 10051 was a
mid-grey/brown silty clay, which contained limited animal bone and a small quantity
of ironworking residue, and had a similarly humic character.
5.14 Ditch 102 was altogether different in size and profile, with moderate to gently-
sloping concave sides with a concave base, and measured an average of 2.54m in
width, and 0.17m in depth. It was investigated by sections 10052, 10083, 10008
and 10098, and ran for 28m, on a straight, south-easterly alignment, from the
northern edge of Area 1, to a point where it met, and was cut by, enclosure Ditch
103. This stratigraphic relationship, which was somewhat diffuse, suggested that
either Ditch 102 had gone out of use by the time Ditch 103 was excavated, or that
they were broadly contemporary, and Ditch 102 had been cut by a recut of Ditch
103. The location of the terminal of Ditch 101, some 3.5m from the northern edge of
Ditch 103, effectively created a small entranceway into what may have been a
formal drove-way entrance represented by Ditches 101 and 102, although this does
not explain the marked differences in profile between the two ditches. Section
10008 of Ditch 102 displayed a width of 3.66m and a depth of 0.25m, with
moderately-sloping sides and an uneven base. It contained a single, secondary fill,
10009, which comprised a mid-grey/brown silty clay, which contained no dateable
material.
Enclosure 1.1: Ditch 103
5.15 Located within the southern half of Area 1 was the Late Iron Age ‘D’-shaped
Enclosure 1.1. This feature had been identified by the geophysical survey, and the
previous evaluation (CA 2015), and was specifically targeted by the excavation of
Area 1. The enclosure comprised a single, continuous curvilinear ditch, Ditch 103
![Page 23: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/23.jpg)

(sections 10090, 10098, 10104, 10111, 10125, 10130, 10137, 10139, 10144 and
10149), of uneven dimensions and profile. This did not form a complete enclosure
circuit, but continued beyond the south-eastern corner of Area 1 on a north-
east/south-west alignment, at which point where it measured only 0.7m in width and
0.34m in depth. Ditch 103 extended 16m from the eastern edge of Area 1, before
turning to the west and extending for a further 25m, where it gradually enlarged to a
width of 2.57m and a depth of 1m. The ditch then turned to the north, and ran on a
curving north-east/south-west alignment round to the north-west, at which point it
had a maximum width of 2.6m and a depth of 1.34m. Ditch 103 then turned at 90
degrees some 9m from the eastern edge of Area 1, and ran for a further 20.5m to
the south-east, becoming progressively narrower and shallower. It terminated just
2m to the north-west of the southerly length of the ditch, close to the point where it
extended beyond the edge of Area 1. At this point, its dimensions had reduced to
0.81m in width and 0.29m in depth.
5.15 Section 10090 was cut on the north-west side of Enclosure 1.1, close to the point of
the widest extent of Ditch 103 (Figs. 3 and 6). This section displayed a width of
2.6m and a width of 1.34m, with steeply-sloping, convex sides and a slightly
concave base. Of the five fills, 10091 was a primary fill of white-brown silty clay, and
10092 was a second primary fill of similar character. Secondary fill 10093 was a
light, grey/brown silty clay, with charcoal and chalk inclusions, and middle
secondary fill 10094 was a mid-white/brown silty clay with charcoal, Period 2 pottery
and a high inclusion of angular chalk. The uppermost secondary fill, 10095, was a
light-grey/brown silty clay, with limited charcoal inclusions, and of slightly humic
character, which may indicate long-term silting processes.
5.16 Section 10111 was cut on the north-east side of Ditch 103, just to the south of the
right-angled turn to the south-east (Fig. 3). This section displayed a width of 1.45
and depth of 0.75m, with steeply-sloping, convex sides and a sub-rounded base. It
contained three fills, of which 10112 was a secondary fill of mid-brown/red silty clay,
with slight chalk and flint inclusions and Period 2, Middle Iron Age sherds. Fill 10113
was a light, yellow-brown silty clay, which contained no finds and may represent the
partial collapse or slumping of ditch sides. The uppermost, secondary fill, 10114,
was a mid-grey/brown silty clay, with angular chalk and flint inclusions, which
contained sherds of Period 2, Middle Iron Age pottery, animal bone and fragments
of fired clay. It may partly represent a deposit of domestic waste, together with the
results of longer-term wind-blown or washed-in sedimentation.

5.17 Section 10130 was cut on the south-west side of Ditch 103, just to the west of
evaluation trench 74. It displayed a symmetrical, V-shaped profile, with steeply-
sloping sides, and a narrow, rounded base. At this location, Ditch 103 measured
1.93m in width and 1m in depth, and contained a sequence of four fills. The
primary fills 10131 and 10132, comprised a white/brown silty clays, representing
weathering deposits. Lower secondary fill 10133 comprised a mid-red/brown silty
clay, containing Period 2 pottery and animal bone, together with 21 fragments of
burnt or fired clay totalling 600g in weight. The upper secondary fill, 10134, was a
mid-red/brown silty clay, with small inclusions of charcoal and chalk, which may
represent the result of natural silting.
5.18 The profile of Ditch 103 varied dramatically, from very steep, slightly convex sides
with a narrow flat base in the north-west, to a gently sloping, concave profile in the
south-east. However, the shallow profile in the south-east appeared to be an
anomaly, with Ditch 103 generally found to have steep convex or concave sides,
and a flat base of varying depth and width. This notable variation in depth has been
attributed to the differential truncation of the enclosure ditch, most probably by post-
medieval and modern cultivation, although the variations are so marked as to
suggest that the changes in depth were deliberate, and may have had a functional
purpose, possibly relating to drainage.
5.19 The stratigraphic relationship between Ditch 102 and Ditch 103 was investigated by
section 11098 (Fig. 3) At this junction, Ditch 102 (cut 10109) was a shallow,
relatively diffuse feature, which contained a single fill, 10110, of mid-brown silty clay
which contained no dateable material. This appeared to be cut by Ditch 103 (cut
10098) at this point, indicating that it was an earlier feature, although it is likely that
Ditch 103 had been subject phases of redefinition or recutting.
Ring gullies 104 and 105
5.20 Located centrally within Enclosure 1.1 were discontinuous lengths of two ring
gullies, 104 and 105. Ring gulley 104 was positioned 1.5m to the north-east of
gulley 105, with both gully lengths positioned concentrically (Fig. 3). Each described
an approximate quarter circle. Gulley 104 (sections 10074 and 10135) contained a
single secondary fill of red/grey/brown silty clay, containing Period 2 Iron Age
pottery. It measured 0.4m in width and 0.18m in depth, and had a moderately-
sloping, concave profile. Gulley 105, by contrast, produced no dateable material.
This feature displayed very steep, concave sides, with a flat base, and measured
![Page 25: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/25.jpg)

0.2m in width and 0.16m in depth. Gullies 104 and 105 had clearly been truncated
to the south and the west, and most probably represent different elements of the
plan of the same roundhouse. The thinner, steep-sided profile of 105 resembled the
slot trenches for stake or plank walling evident in the ring-gulley type of Wessex
roundhouses of Middle Iron Age date (Harding 2009, 71-76). By contrast, the
shallower, wider profile, and a fill of naturally silted character, containing pottery,
suggests that the outer gulley, 104, represents a drip or drainage gulley around the
perimeter of the roundhouse.
Pit and post hole features within Enclosure 1.1
5.21 Post holes 10070 and 10072, and pits 10087 and 10115, were located to just to the
south-west of gullies 104 and 105 (Fig. 3). Although these features did not contain
any dateable material, their position within the roundhouse represented by gullies
104 and 105 suggested that these represented internal structural features of
probable Period 2 date. Post hole 10070 displayed steep, concave sides and a
concave base, and measured 0.47m in length, 0.27m in width and 0.19m in depth.
It was located 2.5m to the south-west of ring gully 105, and contained a single fill,
10071, of mid-grey/brown clay silt. Positioned 1m to the west of post hole 10070
was pit 10087, which measured 1.33m in length, 1.16m in width and 0.31m in
depth, and had a moderately-sloping, concave profile. Pit 10087 contained two fills,
of which 10088 was a yellow/brown clay silt, and 10089 was a secondary fill of
similar character, but darker colouration.
5.22 Post hole 10072 was located 1m to the south-west of pit 10087. It had a steep-
sided concave profile, and measured 0.3m in diameter and 0.16m in depth, with a
single fill, 10073, of mid-grey/brown clay silt. Post hole 10115 was located 5.3m to
the south-east of post hole 10070. It measured 0.46m in width and 0.19m in depth,
with steep, almost vertical, sides, with a flat base, and contained a single fill, 10116,
of mid-grey/brown silty clay.
Features outside Enclosure 1.1
5.23 Pits 10037 and 10107 were respectively located 3m and 7.5m to the north-east of
Enclosure 1.1, and were both sub-circular in plan (Fig. 3). Pit 10037 measured
2.77m in length, 2.57m in width and 0.41m in depth, and had moderately-sloping
concave sides, with a wide, flat base. It contained three fills, of which the lowest,
10038, was a dark-brown silty clay, with flint and chalk inclusions and Period 2
![Page 26: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/26.jpg)

pottery, together with fragments (50g) of fired or burnt clay. The second secondary
fill, 10039, was a dark-brown and white silty clay, with Period 2 pottery, which
represented a dumped deposit of chalk rubble and domestic waste. This fill also
contained 34g of fired or burnt clay fragments. The final secondary fill, 10040, was a
similar, dark-brown silty clay, with flint, chalk and charcoal inclusions, together with
Period 2 pottery and 36g of fired or burnt clay. Pit 10037 was interpreted as a
disposal pit for domestic waste from the closely-adjacent settlement associated with
Enclosure 1.1.
5.24 Pits 10035 and 10041 were located towards the northern corner of Area 1. They
were located on the eastern margin of Area 1 (Fig. 3). Pit 10035 was sub-circular
in plan, with steep concave sides and a flat base. It measured 1.26m in length,
1.09m in width and 0.27m in depth. It contained a single fill, 10036, comprising a
mid-grey/brown silty clay, with chalk inclusions and flecks of charcoal, together with
highly-fragmented Period 2 sherds, and fragments of fired clay and animal bone.
Pit 10041 (Fig. 6)
5.25 Pit 10041 was similar in plan, but had steep, irregular sides and a flat base. It
measured 1.26m in diameter and 0.64m in depth, and contained a sequence of four
fills (Fig. 6). Primary fill 10042 was a light, grey/brown silty clay which may have
derived from the weathering of pit sides. A lower secondary fill, 10043, was a dark,
black/brown sandy silt, with sub-angular chalk and flint inclusions, and a high
inclusion of charcoal, some of which, together with fragments of coke, or burned
coal, and fragments (36g) of fired clay, appeared to represent metalworking or other
industrial debris. This context was rich in finds, including two partly-complete
Middle Iron Age pots (Ra. 3 and Ra. 4), a small iron knife (Ra 1), a metal bead (Ra.
2), a bone comb (Ra. 5), and an item of worked bone (Ra. 6). Two environmental
samples (samples 1 and 2) were taken from this context, which represented a
deposit of burnt and domestic waste. These samples were dominated by weed
seeds, but contained some cereal grains. In addition, samples 6 and 7 were taken
from the contents of pots Ra. 3 and Ra. 4, and were dominated by cereal grains.
These principally comprised barley, with some hulled wheat grains identified as
emmer or spelt. None of the samples taken from fill 10043 contained chaff
elements, or evidence of crop processing waste.
5.26 A further fill of 10041, 10044, was a mid-yellow/brown clay, which represented a
partial collapse of the pit sides. The upper secondary fill, 10045, was a deep
![Page 27: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/27.jpg)

(0.51m) deposit of mid-grey/brown clay silt, with angular flint and chalk inclusions,
which contained Middle Iron Age pottery and a piece of sandstone (SF 2), which
may represent part of a quern. Although the majority or pits within the north-eastern
quadrant of Area 1 contained little or no finds, their spatial relationship to pit 10041,
and discrete grouping to the north of Enclosure 1.1, suggests that they may have
comprised a zoned area of domestic refuse pits. It is likely that evidence of further
pits extends beyond the north-east edge of Area 1.
5.27 Located within the south-eastern corner of Enclosure 1.1, was pit 10096. This was
sub-oval in plan, with moderately-sloping, concave sides and a flat base. It was
located 0.7m to the south-west of the terminal of Ditch 103, and measured 2.01m in
length, 0.88m in width and 0.42m in depth. It contained a single fill, 10097, of mid-
grey/brown clay silt, containing Period 2 Iron Age pottery, chalk nodules and sub-
angular flint. This feature may have been associated with the entranceway into
Enclosure 1.1 on its eastern side, although its shallow, rounded profile suggests
that it was not a post setting.
Period 3: Late Iron Age to Early Roman (c.50BC – AD 75)
Gully 106
5.28 Gully 106 (section 10144) terminated 2m before the south-western edge of Area 1,
and close to the southern-western corner of Enclosure 1.1 This feature ran for 12m,
on a short, south-west/north-east alignment, on the south side of Ditch 103, before
being completely cut by, or incorporated within, Ditch 103. This feature measured
an average of 0.37m in width, and 0.41m in depth, and displayed steep, concave
sides and a concave base. It contained a single fill, 10124, of yellow-brown clay silt,
which included burnt flint, Late Iron Age pottery and animal bone. It is possible that
Gully 106 represents a later phase, or the partial re-cutting, of Ditch 103 of
Enclosure 1.1. On the basis of the Later Iron Age character of the pottery within fill
10124, this feature has been assigned to Period 3, although it appeared to be
integral to an earlier, Period 2 enclosure ditch.
Undated
5.29 Tree-throw hollows 10003 and 10006 were located within the north-western corner
of Area 1, and were sub-oval in plan, with irregular sides and base. They measured
an average of 2.43m length, 1.15m in width and 0.45m in depth. These hollows
were of some interest, as they were the only features identified to the west of Ditch
![Page 28: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/28.jpg)

102. The absence of archaeological features within this area suggested a distinctly
different function across this part of the site, with domestic activity apparently
confined to the south-west facing slope to the north-east of Area 1 and Ditch 102,
while the western side of Ditch 102 was entirely free of structural features and pits,
possibly indicating an open space used for agricultural activity.
5.30 Pit 10107 was positioned between pit 10037 and the eastern edge of Area 1. It
measured 1.95m in length, 1.3m in width and 0.25m in depth, and displayed
moderately-sloping concave sides, with a flat base. It contained a single fill, 10108,
comprising a mid-brown clay silt, with chalk and flint inclusions, but no dateable
material.
Pits 10046 and 10026
5.31 Pit 10046 was located 5.8m to the north of pit 10037. It was sub-oval in plan, with
moderately-sloping, concave sides and a flat base. It measured 0.72m in length,
0.68m in width and 0.15m in depth, and contained a single fill, 10047, comprising a
mid-grey/brown clay silt, with sub-angular chalk and flint inclusions, but no dateable
material. Positioned 9m to the north-west of pit 10046, was large pit 10026. This
was an irregular sub-oval in plan, and measured 3.7m in length, 1.8m in width and
0.4m in depth. It had moderately-sloping concave and convex sides, with a flat
base, and contained two fills. The lower secondary fill, 10027, was a mid-brown
clay silt, with sub-angular flint and chalk inclusions, together with small quantities of
charcoal and animal bone. The upper secondary fill, 10028, was a light-brown and
white silty clay, which represented a deliberate backfilling with natural chalk.
Four-post Structure 1
5.32 Located 1.5m to the east of the north-eastern corner of Enclosure 1.1, was a
discrete group of post holes, comprising cuts 10058, 10060, 10062 and 10064,
which were arranged in a square configuration (Fig. 3). Together, they comprised
clear evidence of a four-post structure. Post hole 10058 was located 1.8m to the
east of the north-eastern side of Enclosure 1.1, and measured 0.39m diameter and
0.15m in depth, and displayed vertical sides with a flat base. Positioned 2.5m to the
north-east of 10058 was post hole 10060, it measured 0.34m in diameter and
0.27m in depth, with vertical sides and a flat base. Post hole 10062 was located
2.6m to the south-east of 10060, and had steep, convex sides and flat base, and
measured 0.36m in diameter and 0.22m in depth. Forming the southern corner of
![Page 29: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/29.jpg)

the structure was post hole 10064, which was located 2.7m to south-east of 10058
and 2.4m to the south-west of 10062. Post 10064 measured 0.36m in diameter and
0.16m in depth and steep sides with a flat base. The single fills of all four post
holes comprised a dark-brown clay silt, with occasional charcoal flecks, but no
dateable material.
Post holes 10066 and 10068
5.33 Post holes 10066 and 10068 were located towards the centre of the eastern
margins of Area 1. They were respectively positioned 3m to the east and south-east
of post hole 10060. Post hole 10066 displayed a vertical northern edge and a
moderately-sloping southern edge, and measured 0.43m in diameter and 0.15m in
depth. Post hole 10068 was located 1m to the south of post hole 10066, it
measured 0.49m in diameter and 0.11m in depth, and displayed a vertical northern
edge, a moderately-sloping, concave southern edge and a flat base. The single fills
of both features comprised mid-grey/brown silty clay, with moderate chalk
inclusions but no dateable material. It appears likely that post holes 10066 and
10068 comprised part of a small, post-built structure, much of which may have
extended to the north-east, beyond the excavation area.
Roundhouse 2 (Figs. 3 and 7)
5.34 Located just to the north of pit 10046, was a discrete group of 11 post holes,
comprising features 10010, 10012, 10014, 10016, 10018, 10020, 10022, 10024,
10029, 10031 and 10033. Of these, 10031 , 10022, 10020, 10024, 10010, 10012,
10014 and 10016 described an irregular circle of c. 5m diameter, and clearly
represented a small, post-built structure of circular plan (Roundhouse 2, Fig. 3,
inset). The constituent post holes commonly displayed moderately-sloping concave
profiles, and were either sub-oval or sub-circular in plan, measuring an average of
0.28m to 0.36m in maximum width, and 0.13m to 0.08m in depth. The fills of these
features commonly comprised mid-grey/brown clay silts, with slight inclusions of
chalk, but no dateable material (Fig. 7). The relatively shallow depth of the post
holes, and the small internal diameter of the structure thus described, suggest that
Roundhouse 2 may not have been a domestic dwelling, and was possibly a
relatively transient feature. It is likely to have represented an ancillary structure,
possibly associated with agriculture, and similar structures have been suggested to
represent roofless animal pens (Harding 2009, 68). None of the post holes
produced any dateable material, but it seems likely that Roundhouse 2 is of
![Page 30: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/30.jpg)

probable Period 2 date, and would therefore have been broadly contemporary with
Enclosure 1.1 and the surrounding pits. As Ditch 101 runs just 0.9m to the west of
the westernmost post hole, 10014, such close proximity might suggest that the two
features were not in use at the same time, although there is equally no indication
that they were not. The lack of dating evidence from either Ditch 101 or the post
holes, together with an apparent lack of any physical or contextual relationship,
precludes any further speculation regarding the relative dates of these features.
However, the two post holes, 10014 and 10016, on the west side of Roundhouse 2,
are located directly adjacent a small sub-rectangular enlargement of Ditch 101, and
may represent an entrance leading directly off the drove-way associated with
Enclosure 1.1.
Posthole 7506
5.35 Located towards the northern end of evaluation Trench 75, posthole 7506 was oval
in plan, with a maximum diameter of 0.5m and a depth of 0.1m. It contained a single
fill, 7507, comprising a mid-red/brown clay silt with sub-angular chalk and flint, but
no dateable material.
Area 2 (Figs. 4 and 8)
5.36 Area 2 contained a complex group of curvilinear gullies and pits which represented
the partly-truncated remains of three probable roundhouses of Middle Iron Age,
Period 2 date. Gulley 202, together with gullies 205/206, pit 20060 and segmented
gulley 20052 represented the incomplete circuit of Roundhouse 3. These features
were partly overlain, and cut, by ring gulley 204, which represented a later
roundhouse (Roundhouse 4), also of Period 2 date. A number of post holes
appeared to describe a sub-circular configuration within gulley 204, and are
therefore likely to represent an inner, concentric circle of structural post settings (Fig.
4). Other post holes appear to represent a comparable circular arrangement of
internal supports for Roundhouse 3. Ring gulley 204 was also associated with a
number of other internal pits and gullies, some of which may have been associated
with internal structural divisions. An external feature, Ditch 203, may represent a
boundary feature associated with the southern entrance of ring gulley 204. An
adjacent length of curvilinear gulley, 201, convincingly represents the remains of a
further roundhouse structure (Roundhouse 5), although this feature extended
beyond the south-western edge of Area 2. Gulley 207, together with paired post
holes, 2066 and 2068, was situated to the north-east of ring gulley 204.
![Page 31: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/31.jpg)

Period 2: Middle to Late Iron Age (c.400 BC to AD 25)
Ring Gulley 201 (Roundhouse 5)
5.37 Ring gulley 201 (section 20072) was partially exposed along the south-western
edge of Area 2 (Roundhouse 5, Fig. 4). It extended from the trench edge on an
east/west alignment, and curved round to the south-east, before terminating at a
distance of 5.8m from the south-western edge of the excavation area. It measured
an average of 0.45m in width and 0.17m in depth, and had a moderately-sloping,
concave profile. Section 20072 displayed a single fill, 20073, of mid-grey/brown clay
silt, which contained small, abraded sherds of Period 2 Iron Age pottery. This fill
appeared to represent a long-term accumulation of windblown or washed-in
sediments. Gulley 201 was interpreted by the excavator as the eastern end of a ring
gulley, which would originally have comprised part of the plan of an Iron Age
roundhouse of similar plan and dimensions to that represented by ring gulley 204.
However, as gulley 201 was only partly exposed within the excavation area, and no
associated features were recorded, such interpretation must remain tentative.
Roundhouse 3
5.38 Located immediately to the east of gulley 201, was gulley 202 (Fig. 4). This
comprised a shallow, 9.2m-long curvilinear feature, which ran from a northern
terminal and curved round to the east for a distance of 9.2m, where it terminated. It
measured an average of 0.54m in width and 0.06m in depth, with a moderately-
sloping, concave profile. It was investigated by sections 20024, 20022 and 20020.
Section 20020 contained a single secondary fill, 20021, of light, grey/brown clay silt
which contained chalk fragments and a small quantity of Period 2 Iron Age pottery.
The excavator suggested that the position of gully 202 indicated an earlier phase of
the roundhouse represented by 204 to the east (Roundhouse 4), which appears
convincing judging by the relationship of gulley 202 to segmented gulley 20052, pit
20060 and gullies 205 and 206, all of which occupy a geometrically circular
configuration, with an internal diameter of c. 11.5m. Collectively, these features
appear to represent a Middle Iron Age roundhouse (Roundhouse 3), which pre-
dated ring gulley 104 (Roundhouse 4), which was partly superimposed upon it.
5.39 Gullies 205 (sections 20036 and 20042) and 206 (sections 20036, 20042 and
20044) were located immediately adjacent to one other, on the northern edge of
gulley 204. Both gullies 205 and 206 were clearly cut by gulley 204, and gulley 206
![Page 32: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/32.jpg)

cut gulley 205 in turn. Both gullies appeared to emerge from beneath gulley 204, on
a north-west/south-east alignment, before curving round to the west. Gulley 205 ran
for 3m before terminating. It had a steep-sided, concave profile, and measured an
average of 0.35m in width and 0.15m in depth. Gully 206 had moderately-sloping
concave sides, and extended for 2.8m before terminating. It measured an average
of 0.35m in width and 0.13m in depth. Section 20036 of Gulley 205 contained a
single fill, comprising mid-grey/brown clay silt, with limited charcoal inclusions, but
no dateable material. This fill appeared likely to represent wind-blown or washed-in
sediments. Gullies 205 and 206 displayed evidence of heavy truncation, and would
originally have formed complete ring gullies which would have curved round on a
circular course to meet gulley 202 at its current northern terminal. Gulley 205
appeared to cut 206, and may therefore represent a re-cutting, or adjustment, of the
ring gulley of Roundhouse 3.
5.40 A number of individual pit or post holes features are situated within an
approximately circular configuration, which lies concentrically within the interpolated
ring gulley representing Roundhouse 3, and plausibly represented a ring of internal
structural supports. These features include post holes 20026, 20012, 20008 and pit
20018, which are also enclosed by ring gulley 204. Conjectural circuits of internal
post settings relating to Roundhouses 3 and 4 are shown on Fig. 4. The absence of
any comparable post hole features relating to Roundhouse 3 outside the circuit of
ring gulley 204 may be attributed to the local effects of truncation, which may also
account for the lack of evidence for gulley 202 in this part of Area 2. The pit or post
hole features were basically sub-circular in plan, and varied from 0.58m (20018) to
0.29m (20012) in maximum diameter, and from 0.8m (20012) to 0.12m (20008) in
depth. Their single secondary fills commonly comprised mid-grey/brown clay silts,
with slight charcoal inclusions, but no dateable material. In some cases (i.e. 20008),
fills included large, sub-angular flints, which were interpreted as post–packing
material. In view of their probable structural association with Roundhouses 3 and 4,
these features have been assigned a Period 2 date.
Roundhouse 4
5.41 Ring gulley 204 was located centrally within Area 2, and comprised a semi-circular
section of curving gully of c. 23m in length, which ran from one north/south-aligned
terminal on the west side, round to a corresponding terminal on the south-east. It
displayed a moderately-sloping, concave profile, and measured an average of 0.4m
in width and 0.14m in depth. Ring gulley 204 was investigated by sections 20038,
![Page 33: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/33.jpg)

20040, 20004, 20046, 20030 and 20028. The single, secondary fill of 20030,
20031, was a mid-grey/brown clay silt, with inclusions of charcoal and burnt flint, but
no dateable material. However, fill 20039 of section 20038 was associated with
Period 2 pottery. Other, similar, fills of this feature, including 20041 (of section
20040), also contained small quantities of Middle Iron Age pottery.
5.42 Segmented gulley 20064 (section 20064) appeared to represent an isolated
surviving element of the original roundhouse plan principally represented by ring
gulley 204. It had a length of 1.2m, a width of 0.48m and a depth of 0.29m, with a
moderately-sloping, concave profile. It contained a single fill, 20065, of mid-
grey/brown clay silt, which contained burnt flint and Period 2 Iron Age pottery.
5.43 Located within the interior space created by ring gully 204 were a number of post
holes, which may represent an internal, concentric ring of structural timber supports
relating to Roundhouse 4. These included pit 20048, post holes 20006, 20004 and
20002, together with the post hole 8404, which was recorded within evaluation
trench 84. These features were generally sub-circular in plan, and displayed
moderate to steeply-sloping, concave profiles, and measured an average of 0.28m
in diameter and 0.09m in depth. Their fills commonly comprised grey-brown clay
silts, with some chalk inclusions. The fill 20049, of pit 20048, included large, angular
flints, which represented post-packing, and partly defined a post pipe within the
centre of the feature. In view of their probable structural association with
Roundhouse 4, these features have been assigned a Period 2 date.
Non-attributed pits and post holes relating to Roundhouses 3 and 4
5.44 A number of the pits and post holes enclosed within Ring gulley 204 do not fall
within the interpolated concentric circuits of internal post-supports relating to both
Roundhouses 3 and 4, and may therefore relate to either structure. These include
the large, irregular pit features 20062 and 20070, and post hole 20010, which
occupied a central position within the projected plan of Roundhouse 3. Post hole
20010 was sub-circular in plan with maximum diameter of 0.18m and depth of
0.07m. It contained a single fill, 20011, of brown/grey clay-silt, which contained no
dateable material. Pit 20062, was a shallow, irregular feature of 1.35m in length and
0.57m in width, with a depth of 0.06m. It displayed a gently-rounded, concave
profile, and contained a secondary fill, 20063, of mid-grey/brown clay silt with chalk
and charcoal inclusions, and highly-fragmented sherds of Period 2 Iron Age pottery.
Pit 20070 was sub-rectangular in plan, with a length of 1.53m, a width of 0.94m,
![Page 34: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/34.jpg)

and depth of 0.15m, with a moderate to gently-sloping, concave profile. It contained
a secondary fill, 20071, of light-brown/grey clay silt, with inclusions of chalk and
highly-fragmented sherds of Period 2 Iron Age pottery. Given their relatively central
position within Roundhouse 3, it is tempting to interpret these two features as the
remains of hearths, although the character of their fills effectively precludes this.
The excavator speculated that, in view of their shallow nature, they could in fact
represent later tree-throw hollows.
Pit 20006 (Fig. 8)
5.45 Pit 20006 was situated immediately to the south of ring gulley 204, but did not
appear to conform to either of the two suggested circuits of internal post supports
relating to Roundhouses 3 and 4. It was sub-circular in plan, with a maximum
diameter of 0.42m and depth of 0,12m, with steep, concave sides and a flat base
(Fig. 8). It contained a single fill, 20007, of light, brown-grey clay silt, with an
inclusion of large sub-angular flints, which may represent post-packing material, but
no dateable finds.
Ditch 203
5.46 Ditch 203 ran for 3.6m out of the southern edge of Area 2, on a broadly east/west
alignment, before terminating. It measured 0.6m in width, and 0.29m in depth, and
displayed steeply-sloping, concave sides and a flat base. It was investigated by
sections 20054, 20057, and pit 8404 (within evaluation trench 84). Section 20057
contained two fills, of which the lower, 20058, was a light-brown silty clay, with high
chalk inclusions, while the upper fill, 20059, was a secondary fill of mid-brown silty
clay, with occasional charcoal and chalk inclusions and Period 2 Iron Age pottery.
This feature did not appear to conform to any of the ring gullies or suggested
roundhouse plans recorded within Area 2, and may therefore represent a surviving
section of contemporary boundary or enclosure ditch.
5.47 Post hole 20068 was located 2m to the north-east of 20066, and was 0.37m in
maximum diameter, with a depth of 0.18m. It contained a similar secondary fill,
20069, which included Period 2 Iron Age pottery. Given the closely-comparable
dimensions and fills of these two features, it is tempting to consider them as
contemporary and thus components of the same structure. Such paired post holes
are a common feature of late prehistoric settlements, although their function has not
been satisfactorily deduced (Harding 1972, 37-8).
![Page 35: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/35.jpg)

Undated
5.48 Other non-attributed features included single post hole 20010, paired post holes,
8413 and 8411 (evaluation trench 84), and 20016 and 20014 respectively. These
were small, sub-circular features, which presumably related to some form of internal
structures within either of the roundhouses. These varied from 0.3m to 0.18m in
diameter, and 0.07m to 0.04m in depth, and contained light-brown/grey clay silt fills
with no dateable material.
Gulley 207
5.49 Segmented gully 207 (sections 20078 and 20080) was located within the northern
corner of Area 2. It displayed moderately-sloping, concave sides with a flat base,
and measured 1.7m in length, 0.72m in width and 0.13m in depth. Section 20078
contained a single secondary fill, 20079, of mid-grey/brown silty clay, with sub-
angular flint and chalk inclusions, but no dateable material. Although gulley 207 was
an isolated, undiagnostic feature, and did not appear to conform to other features
within Area 2, its relative proximity to gullies 204, 205 and 206 suggests that it may
represent part of a contemporary boundary or enclosure which has been largely
removed by plough truncation.
Post holes 20066 and 20068
5.50 The isolated post hole features 20066 and 20068 were respectively located 3m and
5m to the east of ring gulley 204, but displayed no obvious relationship with any of
the roundhouse features identified within Area 2. Post hole 20068 was of Period 2
date, as described in 5.45, above. Post hole 20066 was 0.4m in maximum diameter
and 0.18m in depth, with steeply-sloping sides. It contained a single secondary fill,
20067, of grey/brown silty clay of slightly humic character, which contained no
dateable material.
Pit 20074
5.51 Pit 20074 was located within the space partly enclosed by Gulley 201, and 0.25m
from its inner, south-western edge. This was of sub-circular plan, with a length of
1.2m, width of 0.72m and depth of 0.19m. It displayed moderate to steeply-sloping,
concave sides, with a sub-rounded base. It contained a single secondary fill, 20075,
of mid-grey/brown clay silt with chalk inclusions, but no dateable material.
![Page 36: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/36.jpg)

Area 3 (Figs. 5, 9 and 10) 5.52 Area 3 included three related ditched boundary features, Ditches 301, 302 and 303,
which were difficult to interpret, but appeared to represent part of a funnel-shaped
track-way entrance, or livestock handling system. These ditches were loosely
associated with a number of apparently unrelated post holes and pits, including one
group of nine (Structure 3), which was located towards the western margins of
Area 3, and which appeared to define a small post-built structure of indeterminate
plan. Evidence of a six-post structure and two sets of paired post holes were
situated within the north-west corner of Area 3, while post hole evidence of a
circular building, (Roundhouse 6), in addition to a number of possibly associated
post holes, pits and a four-post structure, were situated towards the north-east
corner of Area 3. Many of these features were undated, although in some cases,
spatial associations with confirmed Period 2 features suggested that they were
broadly of this date. Ditches 301, 302, and 303 and pit 30050 were of Period 3 date,
and may represent a phase of landscape reorganisation within the site, following
the abandonment of Period 2 occupation.
Period 1: Mesolithic to Bronze Age (c.10,000 - 700 BC) (Residual worked flint) 5.53 Period 1 is represented solely by a single item of worked flint, comprising a medial
fragment from a broken flake, which was recovered as a residual item from the
Period 2-dated post hole 30119. This flint is only broadly dateable to the prehistoric
period, and may represent transient Neolithic or Bronze Age activity within the
environs of the Cadnam Farm site.
Period 2: Middle to Late Iron Age (c.400 BC to AD 25) 5.54 Isolated pit 30093 was located 3m to the west of Ditch 301, towards the southern
corner of Area 3 (Fig. 5). It displayed a moderately-sloping, irregular profile and
uneven base, and measured 1.26m in length, 0.49m in width and 0.36m in depth. It
contained a lower fill, 30094, comprising a thin (0.14m) layer of light-grey/brown silty
clay, which included small, sub-angular flints, charcoal, animal bone and Period 2
Iron Age pottery. This was interpreted as a deposit of domestic waste. The upper fill,
30095, was of mid-brown silty clay, which included large flint nodules, charcoal,
animal bone and Iron Age pottery, which appeared to represent a successive deposit
of domestic waste.
Post hole 30104
![Page 37: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/37.jpg)

5.55 Post hole 30104 was positioned along the northern edge of, and was truncated by,
tree-throw hollow 30102, towards the north-east corner of Area 3. It was circular in
plan, with vertical sides and a flat base, and measured 0.6m in diameter and 0.32m
in depth. It contained a single fill, 30105, of mid/dark-grey/brown silty clay, which
contained charcoal and common angular flint, which appeared to have been used
as post-packing material. Two fragments of a sandstone saddle-quern (SF 1) were
found within the top of this fill. Post hole 30104 may be broadly assigned to Period 2
on the basis of this quern, which is otherwise of a type which is only diagnostic of a
late prehistoric date. Post holes 30037, 30063 and 30104 did not appear to
comprise part of any particular structure, but appeared to have some spatial
relationship with Roundhouse 6, and may therefore have been contemporary with it.
5.56 Located to the south-west of the terminal of Ditch 301, were pit 30119 and post
holes 30106 and 30113. Pit 30119 was an elongated oval in plan, with moderately-
sloping, concave sides and a flat base, and measured 0.81m in length, 0.26m in
width and 0.17m in depth. It contained a single fill, 30120, of mid-grey/brown silty
clay, with flint and chalk inclusions, and Period 2 Iron Age Pottery. This fill also
contained the single, residual find of worked flint recorded on the site, comprising a
medial fragment of a broken flint flake, which could only be broadly dated to the
prehistoric period (Sommerville, this report).
Post hole 30151
5.57 Isolated post hole 30151 was located equidistant from Ditches 301 and 302, i.e.
9.5m from each. It was sub-oval in plan, with a moderately-sloping, concave profile,
and measured 0.74m in length, 0.51m in width and 0.17m in depth. It contained a
single, secondary fill, 30152, of dark-brown/grey silty clay, which included sub-
angular flint, charcoal and Iron Age pottery. The humic character of this fill, together
with the presence of Period 2 pottery, suggested that 30151 was not a structural
feature, but contained a deposit of domestic waste.
Post holes 30156 and 30159
5.58 Located respectively 4.5m and 5.5m south-east of post hole 30151, were post holes
30156 and 30159. They were both sub-circular in plan, with steep, concave profiles.
Post hole 30156 measured 0.68m in maximum diameter, and 0.26m in depth. It
contained a primary fill, 30157, of mid-yellow clay silt, and a secondary fill, 30158,
of mid-grey/brown clay silt, which included small quantities of chalk and charcoal,
![Page 38: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/38.jpg)

but no dateable material. Post hole 30159 measured 0.53m in maximum diameter
and 0.24m in depth, and contained a single fill, 30160, of mid-grey/brown clay silt
with inclusions of chalk and Period 2 Iron Age pottery, together with small quantities
of vitrified hearth/furnace lining, cinder and fired clay (71g). In view of their close
proximity and comparable dimensions and fills, it is possible that post holes 30156
and 30159 are contemporary, and therefore comprised part of the same,
unidentified structure. On the basis of the pottery from the fill of 30159, these
possibly paired features have been assigned a Period 2 date.
5.59 Pit 30149 had a length of 0.6m and width of 0.35m, with a depth of 0.17m. It
contained a single fill, 30150, of mid/dark-grey/brown clay silt, which included burnt
flint and Period 2 Iron Age pottery.
Period 3: Late Iron Age – Early Roman (c. 50BC- AD 75) (Figs. 5, 9 and 10) Pit 30050
5.60 Pit 30050 was located 2m to the west of Ditch 302, and c. 9m to the south of its
northern terminal. It was sub-rectangular in plan, with steep, concave sides and a
flat base, and measured 1.95m in length, 1.1m in width and 0.65m in depth. It
contained three fills, of which 30051 was a primary fill of 0.52m depth, comprising
light-yellow/brown chalky clay, with inclusions of sub-rounded flint and Period 3 Late
Iron Age/Early Roman pottery. Secondary fill 30052 was a homogenous, mid-brown
clay silt, which included fine, sub-rounded flint, charcoal, 13 fragments of fired clay
(917g), and ironworking residues which comprised 156g of smithing-hearth bottom.
This fill has been interpreted as a deposit of industrial waste. An upper secondary
fill, 50053, was cut into the top of fill 30052, and comprised a light/mid-brown clay
silt, containing chalk and flint inclusions and Period 3 pottery.
Ditch 301 (Fig. 9)
5.61 Ditches 301 (sections 30123, 30126 and 30146), 302 (sections 30100, 30108,
30140 and 30143) and 303 (sections 30137 and 30153) were located within the
southern half of Area 3, and appeared to form elements of a rectilinear-plan drove-
way entrance, which terminated towards the centre of Area 3. Ditch 301 extended
from the south-western corner of Area 3, on a broad north-south alignment, for
21m, after which it turned to the north-west and ran for a further 8m before
terminating. Section 30123 displayed a steep, concave, but symmetrical, profile,
![Page 39: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/39.jpg)

which measured 0.90m in width and 0.47m in depth (Fig. 9). It contained two
secondary fills, of which the lower, 30124, was a mid-red/brown clay silt with chalk
inclusions, which contained small quantities of Period 3 pottery and animal bone.
The upper fill, 30125, of mid/dark-grey/brown clay silt, with flint and charcoal
inclusions, and containing Period 3 pottery and animal bone. Both ditch fills
probably represent deposits of domestic waste. Secondary fill 30142, of section
30140 of Ditch 301, contained 75g of undiagnostic ironworking debris, together with
two fragments of fired or burnt clay, weighing 44g. Sample 4 from this fill was
dominated by barley grains, with a few grains of hulled wheat and seeds of
clover/medick. No chaff elements were present in this sample, suggesting that the
grain had been cleaned. Elsewhere, there was little evidence of plant remains within
the fills of Period 3 ditches. Sample 3, from the secondary fill 30139, of section
30137 of Ditch 303, contained only a single barley grain, and no other plant
remains, while sample 5 from the dark, brown/grey secondary fill, 30128, of section
30126 of Ditch 301, contained no plant remains. Further fragments of fired clay
(49g), possibly derived from industrial activity, were recovered, along with animal
bone, from fill 30110 of section 30108, of Ditch 301.
Ditch 302 (Fig. 9)
5.62 Ditch 302 extended for 11m from the south-eastern edge of Area 3, on a south-
west/north-east alignment, before turning to the east and running for a further 8m,
after which it turned through a 90° angle to the north-west, and then ran for a further
22m before terminating. Section 30108 displayed a rounded, concave profile, and
measured 1.56m in width and 0.44m in depth. Section 30143, by contrast,
displayed steeply-sloping sides and a rounded base, and measured 1.11m in width
and 0.43m in depth (Fig. 9). Section 30108 contained a primary fill, 30109, of light-
grey/brown silty clay, and a secondary fill, 30110, of grey-brown silty clay, which
contained animal bone, but no dateable material. Ditch 302 cut an earlier tree-throw
hollow (30111) at this point. Section 30140 demonstrated that Ditch 302 also cut,
and possibly superseded, the earlier Ditch 303 at this point. In view of its spatial
relationship with Ditches 301 and 303, and as clearly part of the same scheme of
ditched features, Ditch 302 was assigned a Period 3 date.
Ditch 303
5.63 Ditch 303 was cut by, and extended from, Ditch 302, at a point 6m from the south-
eastern edge of Area 3. It then ran for 8m, on a south-west/north-east alignment,
![Page 40: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/40.jpg)

before terminating. Ditch 303 appeared to represent an earlier phase of Ditch 302.
Section 30153 displayed steeply-sloping sides and a rounded base, and measured
0.9m in width and 0.28m in depth. It contained a primary fill, 30154, of light-
yellow/red silty clay, and a secondary fill, 30155, of dark, grey-brown silty clay with
charcoal and flint inclusions, and containing animal bone and Period 3, Late Iron
Age pottery.
Undated
Six-post structure
5.64 Within the north-western corner of Area 3 was located a discrete group of post
holes, comprising cut features 30003, 30005, 30007, 30009, 30011 and 30014.
These were positioned in two parallel lines, each of three post holes, and arranged
on south-west/-north-east alignment, thus clearly representing a six-post structure
(Fig. 5). The individual post holes were sub-circular in plan, and displayed steep,
vertical sides with a concave base, and measured an average of 0.31m in length,
0.2m in diameter and 0.26m in depth. They contained single fills of mid/dark-brown
and yellow-brown silty clays, which contained no dateable material.
Area 3 Post holes
5.65 Single post hole 30017 was located 1.8m east of post hole 30014, it was circular in
plan, and displayed a steep, concave profile and measured 0.2m in diameter, and
0.1m in depth, with a fill of yellow-brown chalky clay. It contained no dateable
material. Positioned 6m to the south-east were paired post holes 30025 and 30027,
which were separated by a distance of 0.75m. These features displayed gently-
sloping concave sides, with flat bases, and measured 0.32m in maximum diameter,
and 0.1m in depth respectively. Their fills comprised dark, brown-black silty clay,
which contained a small amount of charcoal, but no dateable material. These post
holes are amongst a number of similar, paired features on this site, which appear to
represent simple structures of uncertain function (Harding 1972, 37-8).
5.66 Positioned centrally along the northern edge of Area 3, were post holes 30019,
30021 and 30023, of which the latter two appeared to be paired, and separated by
a distance of c. 0.75m. Post hole 30021 was positioned to the south-west of 30023,
with 30019 located a further 2.2m to the east. These were all sub-circular in plan,
with steep, concave profiles, and measured on average 0.24m in length, 0.12m in
![Page 41: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/41.jpg)

width and 0.20m in depth. They contained mid/dark-brown silty clays, with
inclusions of small, angular flints and occasional charcoal, but no dateable material.
Post hole 30069
5.67 Within the north-eastern corner of Area 3 was a discrete group of 23 post holes and
two pits. Of these, post hole 30069 was located 3.1m north-west of post hole
30045, it did not appear to relate to any pattern or structure defined by the nearby
group. It measured 0.32m in length, 0.2m in width and 0.09m in depth and
displayed gently-sloping, concave sides, with an irregular base. Its single fill, 30046,
comprised a chalky, yellow-white silty clay, which contained no dateable material.
Roundhouse 6 (Fig. 5)
5.67 To the south-east of post hole 30069, were located post holes 30033, 30035 (Fig.
10), 30039, 30045, 30048, 30054, 30060 and 30079, in addition to the post holes
2606 and 2608, which were identified within Trench 26 of the evaluation.
Collectively, these features described a small post-built structure of circular plan,
with an internal diameter of c.6m (Roundhouse 6, Fig. 5). The majority of these
post holes displayed vertical sides with concave bases, and measured an average
of 0.30m in length, 0.18m in width and 0.2m in depth. Their fills comprised silty
clays, ranging from dark-brown to light-yellow/brown in colour, with some chalk and
flint inclusions but no dateable material. The mode of construction certainly
suggests a Period 2 date, and while these features remain technically undated, an
adjacent post hole, 30104, contained fragments of saddle quern within its upper fill,
suggesting that a Period 2 date could probably be assigned to Roundhouse 6.
5.68 Located within the interior of Roundhouse 6 was post hole 30071. This displayed a
maximum diameter of 0.44m and a depth of 0.28m, with steeply-sloping sides and a
U-shaped profile. It contained a single fill, 30072, which comprised a pale
grey/brown silty clay, with chalk and flint inclusions, but no dateable material.
Pit 30073
5.69 Pit 30073 was located 1m west of the eastern edge of Area 3, and 2.8m to the
north-east of Roundhouse 6. It was sub-circular in plan, with moderately-sloping
sides and a flat base, and measured 1.6m in maximum diameter and 0.3m in depth.
It contained a single fill, 30074, of mid-brown silty clay, which contained a very high
inclusion, comprising up to 50% of the fill, of large, angular flint nodules, some of
![Page 42: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/42.jpg)

which had been fire-affected. No charcoal or dateable finds were recorded in this
fill. The partly-burnt nature of the flints suggested that this material may have
comprised part of a hearth, or some other fire-related structure.
Four-post Structure 2 (Fig. 10)
5.70 Located 0.6m to the south-east of post hole 30039, was post hole 30029 which,
along with post holes 30031, 30041 and 30043, formed a four-post structure (Four-
post Structure 2, Figs. 5 and 10). Post hole 30029 formed the north-western corner
of the structure, and was located 0.8m south-west of post hole 30031, and 1.3m
north-west of post hole 30041. The south-eastern corner of the structure was
formed by post hole 30043, this was positioned 1.3m south-east of post hole 30031,
and 0.9m north-east of post hole 30041. The post holes displayed steep, vertical
sides with flat bases, and measured an average of 0.53m in maximum diameter and
0.35m in depth (Fig. 10). Their fills comprised light-grey/brown silty clay, which
contained large flints which had been included as post-packing material. Some of
this flint had been burnt. The fill, 30042, of post hole 30041, contained small
quantities of pottery of broadly late prehistoric date. On this basis, and in view of
the established date-range of comparable four-post structures elsewhere, Four-post
Structure 2 could be assumed to be of Period 2 date. The large dimensions of
these post holes, and the use of post-packing material, suggest that this structure
would have been fairly substantial (see Lambrick 2014, 136).
Structure 3
5.71 Structure 3 comprised a tightly-clustered group of nine post holes, comprising
features 30091, 30098, 30089, 30085, 30083, 30081, 30087, 30096 and 30130 (Fig.
5). The seven smaller post holes averaged 0.22m in diameter, with shallow depths
of between 0.06m and 0.19m, and were generally sub-circular in plan. Their single
fills comprised grey-brown silty clays, which contained no dateable material. The
irregular configuration of these features does not readily suggest a coherent plan,
and the structure, if such it was, would have had a maximum diameter of only 2.5m.
It is possible that these features represent more than a single phase of construction,
and the distinctly larger size of post holes 30098 and 30130 (respectively 0.40m and
0.38 in width) may suggest that these had a different structural function. Structure 3
is considered likely to represent an agriculturally-related structure, of possible Period
2 date.

Post holes 30037, 30063 and 30104
5.72 The remaining features within the north-eastern corner of the site comprised post
holes 30037, 30063 and 30104 (Fig. 5). Post hole 30037 was circular in plan, with
an irregular profile, and measured 0.44m in maximum diameter and 0.12m in depth.
It contained a single fill, 30038, of mid-yellow/brown silty clay, with moderate flint
inclusions, but no dateable material. Post hole 30063 was positioned 2.5m to the
north-east of post hole 30037. It was sub-oval in plan, with concave sides and a flat
base, and measured 0.73m in length, 0.34m in width and 0.17m in depth. It
contained a single secondary fill, 30064, of mid/dark-brown silty clay, which
contained no dateable material.
Individual pits to the west of Ditch 301
5.73 Pits 30134 and 30149 were positioned 1.9m apart, close to the south-western
margins of Area 3, and respectively 4.4m and 3.3m south-east of post hole 30130
(Fig. 5). Both pits were sub-oval in plan, and had moderately-sloping, concave
profiles. Pit 30134 had a maximum diameter of 0.79m and depth of 0.22m. It
contained two fills, of which the lower, 30135, was a mid-grey/brown silty clay,
which inclusions of angular chalk, flint and charcoal, but no dateable material. The
upper fill, 30136, comprised a dark-grey/brown clay silt of distinctly humic character,
which included angular flint and charcoal, but no dateable finds. This was
interpreted as a deposit of domestic refuse. Pits 30134 and 30149 appear likely to
represent paired features.
5.74 Post holes 30106 and 30113 were positioned 1.5m apart, and appeared to be
paired features. They were both oval in plan, with steeply-sloping, concave profiles.
and measured an average of 0.44m in length, 0.23m in width and 0.25 in depth.
Both contained fills (30107 and 30114 respectively) of mid-grey/brown silty clay,
with inclusions of flint and charcoal, but no dateable material.
Pits and post holes located between Ditch 301 and Ditch 302
5.75 A group of four post holes, comprising cut features 30115, 30117, 30161 and
30163, were positioned on a broad east-west alignment, slightly to the east of the
terminal of Ditch 301. The closest post hole, 30161, was located 1.8m to the east
of this terminal, and post holes 30115, 30117 and 30163 were respectively located
2m, 2.3m and 3.3m to the east of post hole 30161. These features were all sub-
circular in plan, with steeply-sloping, concave profiles. They measured an average
![Page 44: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/44.jpg)

of 0.26m in diameter and 0.14m in depth, and contained single clay silt fills, which
varied in colour between mid-red/brown and dark-grey/brown. These contained
small inclusions of flint, but no dateable material. Their close spatial association
and proximity to the terminal of Ditch 103 suggested that they may represent a
structure, possibly a gate or fence, associated with the function of Ditches 301 and
302, although such an association was not confirmed by excavation, and these
features consequently remain undated.
5.75 Post holes 1607 and 1605 were identified within evaluation trench 26. They were
respectively located 6.5m and 2.5m to the south-west of the terminal of Ditch 303,
of which they appeared to represent some form of westward continuation. Post
hole 1607 was of circular plan, with near-vertical, concave sides and a flat base. It
measured 0.57m in maximum diameter and 0.08m in depth, and contained a single
fill, 1608, of mid-brown clay silt with sub-angular flint inclusions. Post hole 1605
was of oval plan, with gently-sloping, concave sides, and measured 0.73m in
length, 0.5m in width and 0.12m in depth. It contained a single fill, 1606, of dark-
grey/brown clay silt, with flint, chalk and charcoal inclusions. Neither of these
features contained dateable material.
Three-throw hollows
5.76 Area 3 contained three tree-throw or tree-root hollows, all of which were partly cut
by archaeological features. Tree-throw hollow 30102 was located 1m to the north-
east of post hole 30031. It was sub-oval in shape, and displayed moderately-
sloping, irregular concave sides and a concave base, and measured 2.93m in
length, 1.7m in width and 0.5m in depth. It contained a bioturbated mid-grey/brown
silty clay fill, and was cut on its northern side by Period 2 post hole 30104.
5.77 Tree-throw hollow 30134 was located to the south of, and was truncated by, post
hole 30130, it was sub-oval in shape, with a gently-sloping, concave profile, and
measured 0.79m in length, 0.69m in width and 0.22m. It contained a mid-
grey/brown silty clay fill, and was cut at its northern extremity by undated post hole
30130. Tree-throw hollow 30111 was truncated on its western side by Ditch 302.
As excavated, it displayed steep, concave sides, and measured 1m in length,
0.47m in width and 0.2m in depth, with a fill, 30112, of light, grey-brown silty loam.
As the tree-throw hollows contained no dateable material, and appeared to be
archaeologically sterile, it is probable that they pre-dated Periods 2 and 3.

Area 3 features recorded by Evaluation
5.78 Three undated post holes were recorded towards the south-west end of Trench 26.
These displayed maximum diameters of 0.3m, and were arranged in a short arc, at
intervals of c. 0.63m (Fig. 5). It was suggested by the excavator that these might
represent a further, small post-built structure of c.3.2m diameter (CA 2015),
although no other post holes which would have confirmed a circular plan were
evident elsewhere within Trench 26. These post holes contained single fills of mid-
red/brown clay silt, but no dateable material.
5.79 Two post holes, 2606 and 2608, were recorded further to the north-east within
Trench 26, and these were confirmed by excavation to comprise part of the circuit
of post hole features representing Roundhouse 6. These post holes displayed
maximum diameters of 0.36m, and depths of 0.30m, and contained single fills of
mid-red/brown clay silt, with sparse charcoal inclusions but no dateable material.

Worked and burnt flint by Jacky Sommerville
6.2 One worked flint (1g), and a total of at least 77 pieces of burnt, unworked flint
(4741g) were recovered from the excavation of 18 separate deposits. The lithic finds
are of minimal archaeological significance.
6.3 The worked flint comprises a single medial fragment from a broken flake, which was
retrieved from Period 2-dated pit/posthole 30119, in Area 3. This find is only broadly
dateable to the prehistoric period, and is a redeposited item within this feature.
6.4 The burnt flint was recorded in pit and ditch/gully fills, all of which were dated to the
Iron Age on the basis of associated pottery. The burnt flint is broadly representative
of domestic activity, including cooking or water heating.
Pottery by E.R. McSloy
Late Prehistoric pottery (including Late Iron Age/Early Roman ‘transitional’)
6.5 Pottery amounting to 622 sherds (7900g) was hand-recovered from the excavation,
from 56 separate deposits. This assemblage includes some 156 sherds (1711g)
recorded from the evaluation, and reported on elsewhere. The quantification by area
of the pottery (Table 7), together with fabric descriptions, are summarised in
Appendix B of this report.
6.6 The pottery has been fully recorded; scanned by context, sorted by fabric and
quantified according to sherd count, weight and rim EVEs (estimated vessel
equivalents). Where identifiable, vessel form (profile) and rim morphology were also
recorded, as were decoration/surface treatment and attributes, including sherd
thickness-range, and evidence for use (residues and use wear). Summary fabric
descriptions, with codes used for recording, are given in Appendix B of this report.
6.7 The excavated pottery assemblage relates to three areas, with the largest quantities
coming from Areas 1 and 3 (Table 7, Appendix B). The majority was recovered from
discrete pit/posthole features (326 sherds or 67.1%), including a group of 173
![Page 48: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/48.jpg)

sherds from one feature, Area 1 pit 10037. Pottery recorded from the evaluation was
largely derived from areas later targeted for excavation: Trenches 13-14, 16 and 24-
26 (located close to Area 3) produced 67 sherds weighing 608g and Trenches 74-79
and 82-85 (near to Areas 1 and 2) some 52 sherds, weighing 1010g.
6.8 The condition of the pottery assemblage was mixed; surface preservation is
frequently poor, particularly amongst the quartz-tempered group, where surfaces are
friable/powdery. The mean sherd weight (12.7g) is moderately high for a prehistoric
group, and not suggestive of high levels of disturbance. The degree of fragmentation
is, however, very variable, with the larger/joining vessel sherds limited to a small
number of better-preserved groups, including from Area 1 pits 10037 and 10041. Of
particular note is ‘saucepan pot’ no. 6, which recorded from Evaluation Trench 79,
posthole 7907, and deposited intact.
Assemblage range
Fabrics
6.9 The composition (fabrics range) of the assemblage is set out in Table 7 by area. The
large majority of this group consists of handmade types, among which flint-tempered
and quartz-tempered types are strongly dominant, although the quartz-bearing types
are markedly less well represented among the Area 3 group (Table 7).
6.10 Both the dominant fabric groupings are representative of common traditions for the
period encountered across Hampshire. Typically, as here, flint-tempered fabrics are
dominant, although proportions of the main flint and quartz-bearing types are
variable from Hampshire sites (Hawkes 1985, 60; Hawkes 1987, 24-25; Rees 1995,
37, fig. 23), and at sites such as Brighton Hill South (Rees 1995, 37), where
proportions commonly vary relative to internal site chronology. The use of crushed,
burnt flint has pre-Iron Age origins, and continued throughout the Iron Age and into
the Early Roman period. In an area of chalk geology, pottery utilising flint-tempering
can be expected to be local in origin. Similarly, the sources for the quartz-bearing
types might be local, most likely sands within the Reading Beds or the Lower
Greensand, both within 10km of the site. The remaining fabrics are similarly
representative of types seen from other Iron Age/Early Roman groups from the area.
The only non-local type is a shell-tempered fabric recorded from enclosure ditch
10130 (fill 10133). Wheel-thrown fabrics which date to the Late Iron Age/Early
![Page 49: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/49.jpg)

Roman transition are restricted to a small number of sherds recovered from Area 3
ditch 30123 (fills 30124, 30125).
6.11 The basic range of pottery forms is as follows:
Forms
V1 Slack-shouldered forms (probably jars); upright or slightly everted necks with simple or
squared rim tops. Size range 160-260mm (diam.). 3 vessels (0.16 EVEs). Fig. *, no. 1. V2 Globular-bodied vessels (probably jars). Neckless or with short, uprirght or everted neck and
simple or bead-like rims. Size range 140-220mm (diam.). 8 vessels (0.39 EVEs). Fig. *, nos. 2-4, 9.
V3 Ovoid or barrel-shaped vessels (jars)/’incurving saucepan pots’. Neckless with simple rims. Size range 90-180mm (diam.). 4 vessels (0.32 EVEs). Fig. *, no. 5.
V4 Straight-sided vessels (jars) in Saucepan pot tradition. Neckless, with simple or bead-like
rims. Size range 160-180mm (diam.). Decoration as all-over burnish or horizontal burnish lines at base angle. 5 vessels (1.15 EVEs). Fig. *, nos. 6-7.
V5 Angular-shouldered vessels (jars or bowls).Neckless, and with bead rims. Size range 120-
160mm (diam.). 2 vessels (0.13 EVEs). Fig. *, no. 10.
V6 Large jars; globular or ovoid-bodied with everted rims. Size range 200-300mm (diam.). 2 vessels (0.24 EVEs). Fig. *, no. 11.
V7 Wheelthrown vessels (necked jars or bowls). Size range 150mm (diam.). 1 vessel (0.12 EVEs). Fig. *, nos. 12-13.
6.12 The range of vessel forms is set out for the assemblage above complete. Further
vessels, were represented by smaller rim sherds, where the vessel form (profile) was
uncertain. Most are almost certainly additional examples of the forms described
above, and the assemblage is clearly dominated by jar-proportioned vessels which
are likely to have been utilitarian in function. Decorated fineware bowls of the styles
seen elsewhere (though rarely) amongst Middle Iron Age groups from Hampshire
(Hawkes 1985, 66, fig. 54; Rees 1995, 41-42, figs. 24-25) were not recorded.
Instances of decoration are very few (five vessels), and are limited to scored or
burnished lines to some ‘saucepan pot’ vessels or overall burnish, also to vessels in
this class. One body sherd (deposit 10045) exhibits more elaborate decoration, as
burnished line decoration in a crosshatch pattern, and one vessel of form V2
features light scoring/brushing below its shoulder.
Stylistic affinities and dating
![Page 50: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/50.jpg)

6.13 The large majority among this assemblage can be compared with styles
characterising pottery of the Middle and later Iron Age in the region, with a very few
vessels (from Area 3) suggesting continuity of activity into the mid-1st century AD.
The furrowed and other angular bowl styles, or fingertip-decorated vessels, which
commonly characterise pottery in the Late Bronze Age to Early Iron Age transitional
period (c. 8th to 5th centuries BC) are absent. The slack-shouldered, globular and
neckless vessels (forms V1-V3), the majority from Area 1, are more characteristic of
the plainer styles beginning in the earlier Middle Iron Age (4th/3rd centuries BC).
These compare, for example, to vessels from Phase 1 (Early–Middle Iron Age) at
Brighton Hill South, near Basingstoke (Rees 1995, 41, fig. 24).
6.14 The ‘saucepan pot’ style, which is here confined to vessels from Area 1 (and
Evaluation Trench 79), similarly has earlier Middle Iron Age origins, as early as the
4th or 3rd centuries BC, from Danebury, Hampshire, and Gussage All Saints, Dorset.
The style may be long-lived, continuing into the 1st century BC (Cunliffe 2005, 627),
and there is evidence to suggest that plainer styles, such as those represented at this
site, are typical for the later Middle Iron Age. Although difficult to argue from such a
small assemblage, it is possible that the plain, straight-sided saucepan pots are
representative of later Middle Iron Age activity. The best evidence for this may be
their absence from pit group 10037, the pottery from which is most suggestive of an
earlier Middle Iron Age date.
6.15 There is a quite clear stylistic separation evident between groups from Areas 1/2 and
3, and differences are also evident in the ranges of fabrics represented (Appendix B,
Summary Fabric Descriptions). Although the number of identifiable forms is small,
there is an absence of the earlier classes seen from Areas 1/2. The handmade bead
rim and large everted-rim jar forms which are present, compare more closely with the
Late Iron Age or ‘transitional’ styles represented, for example, among deposits dating
to the 1st centuries BC/AD at Silchester (Timby 2000). The small number of vessels
from this area occurring in wheel-thrown grog-tempered and sandy fabrics may be
contemporary, and suggest a dating-range extending into the middle, or later, 1st
century AD.
Discussion 6.16 Stylistically and technologically this small assemblage accords with the established
material recorded for the Middle and Later Iron Age across the wider sub-region
(Hampshire). Comparisons across the Area 1/2 and 3 groups reveal differences
![Page 51: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/51.jpg)

which reflect differing chronologies, with Area 3 clearly the later. The stylistic
differences apparent from the larger context groups from Areas 1 and 2 suggest that
activity may have been of sufficiently long duration to encompass a change in
ceramic styles.
6.17 A further aspect of the assemblage, which invites comparison with contemporary
groups from central-southern England, is the apparent examples of ‘structured
deposition’ within the site. Most obvious in this regard is the vessel deposited intact
within the small pit/posthole feature 7908 of evaluation trench 79. Material from the
Area 1 pit 10041 represents a further probable example, with the pottery from this
feature occurring as larger and possibly freshly-broken sherds and in close
association with artefacts of a probable domestic origin (an iron knife, worked bone
weaving comb fragments and a quantity of birch bark tar), which are otherwise rarely
represented at the site. This combination of artefacts within this context must identify
pit 10041 as unusual, and comparable to the ‘structured’ pit groups which are a noted
feature of Iron Age Wessex, and discussed in greater detail by Hill (1995) inter alia.
The ‘selection’ of straight-sided saucepan pots may also be significant; this style
being among the few exhibiting any ‘embellishment’ (burnishing).
6.18 The pottery assemblage provides no clear indication of the economic status of the
original users. The virtual absence of certainly non-local pottery, or of what might be
recognised as ‘finewares’ (i.e. decorated bowls), might suggest an insular community
with a limited requirement for ‘non-utilitarian’ pottery. It is the case, however, that
decorated or other ‘finewares’, and regionally-traded types, are generally uncommon
within Middle Iron Age assemblages from this area, including those from Oram’s
Arbour, Winchester, where a degree of elevated status is implied only by the nature
of the site (Holmes et. al. 2004).
Items of Worked Stone by Ruth Shaffrey
6.19 Three fragments from two stone querns were recovered during the excavation. One
is a probable quern fragment of coarse gritty sandstone (SF 2), from fill 30072, of
post hole 30071. This context suggests that it may have been used as post-packing
material. It exhibits one flat, pecked face. The other example comprises two
adjoining fragments of a sandstone saddle-quern, which together represent
approximately 90% of the original quern (SF 1). This was found within the top of the
![Page 52: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/52.jpg)

fill, 30105, of post hole 30104, and may represent a deliberately-placed item. It has
been used, so that it is of worn, slightly concave form, both across and lengthways.
Both querns appear likely to be from a nearby Upper Greensand exposure, though a
precise source has not been identified. The items of worked stone are catalogued in
Table 8 (Appendix C) of this report.
6.20 The querns have limited potential to add to our understanding of Iron Age domestic
activity at the Cadnam Farm site, and may be considered alongside other domestic
artefacts, particularly those from pit 10041. The context of the deposition of the
saddle quern (SF 1) is of some interest, as this may relate to the life of Roundhouse
6. It is possible, however, that the two fragments were deposited separately within
the feature, and that the quern could have been deliberately broken prior to
deposition. The stone types used for both querns merit comparison with those from
other sites, as relatively little is known about local Greensand sources.
Metalworking Debris by David Starley
Summary 6.21 The very small amount of metalworking debris recovered from excavations at
Cadnam Farm, totalled just less than 400g. Visual examination identified the
diagnostic material as derived from iron smithing activity. Contextual analysis may
indicate whether this activity was linked to the occupation of the site, or merely
represents a general off-site distribution of debris from ironworking in the locality. A
summary of the metalworking debris, including a quantification by context, is given in
Table 9, in Appendix D of this report.
Methodology for assessment of metalworking debris
6.22 A total of 391g of metalworking debris from the Cadnam Farm excavation was
visually examined and tested with a streak plate. A magnet was also used to check
any fine debris in the bags for hammerscale, and a flame test was used to confirm
the identity of coke. The debris having been thoroughly washed, very little fine, loose
material was found within the bags. The material was classified into the categories
used by the specialist, which are based on those developed by the former English
Heritage Ancient Monuments Laboratory. Table 9, Appendix D, presents a summary
of these findings, including a full listing, by context.

Classification of debris (Table 9)
1. Diagnostic - Iron smithing
6.23 A single, relatively small smithing-hearth bottom was identified from the fill (30052)
of pit (30050). These fayalitic (iron silicate) plano-convex blocks form in the base of
a smithing hearth, as a result of the reaction between iron-scale and a source of
silica, either the clay lining or any sand used as flux. They are distinctive, and
provide good evidence of iron smithing, but may have been moved some distance
from the site of working. Unfortunately, no micro-slags, flake or spheroidal
hammerscale, which provide a surer indication of the site of any blacksmithing
(Starley 1995), were found within the bulk bags.
2. Non-diagnostic ironworking
6.24 Two contexts, the fill (30142) of a Ditch 301 (30140), and a pit (30159), produced
debris of a similar fayalitic composition, but not of distinctive form. These were
classed as undiagnostic ironworking slags, as similar material is produced during
iron smithing and smelting processes. However, it is more probable that these also
derive from iron smithing.
3. Metalworking or other high temperature processes.
6.25 This group included a range of debris associated with the heating of a variety of clay
structures, possibly including hearths, furnaces, kilns, domestic ovens, inadvertently-
burned daub or other sources. While fired clay is the less severely-heated material,
and could possibly derive from a domestic hearth, it should be noted that even
metallurgical hearths and furnaces have regions of relatively low temperature.
Vitrified hearth lining is clay that has been subjected to severely high temperatures
and chemical attack on its outer surface, whilst cinder shows an all-over vitrification
of clay that has spalled away from the hearth/furnace wall. The latter two categories,
while not diagnostic of ironworking, may well also have resulted from this activity,
and it should be noted that both the cinder and hearth/furnace were found in a
context that also produced undiagnostic ironworking slag.
4. Fuel
6.26 A single sample from fill 10043 contained a mixture of charcoal and coke, or
possibly partially-burned coal. As the use of coke as a fuel is a relatively recent
innovation, this link with charcoal was unexpected, whether or not this had any
association with metalworking.

Discussion and conclusions 6.27 The debris is not stylistically datable. The examination of a relatively small sample of
metallurgical debris from the site indicated that iron smithing was the definite source
of one fragment, and the probable origin of much of the other debris. This was either
carried out on a very small scale, possibly by an itinerant ironworker, or the debris
may have diffused to this site from a larger ironworking operation within in its vicinity.
In either case, ironworking does not appear to have been of particular economic
importance to the occupants of the site. Any further spatial or chronological analysis
of the debris is beyond the scope of this assessment.
6.28 While it was noted that all the metallurgical debris came from Area 3, the distribution
of this material within Area 3, and the dating of the features concerned, has not been
assessed within this specialist report. No focus for ironworking activity has been
identified within Area 3, although it is possible that a number of phases of such
activity are represented within the fills of Period 3 features.
Fired Clay by Katie Marsden
6.29 A total of 73 fragments (1971g) of fired clay was recorded from 15 deposits. The
majority of fragments occur in a soft, pale buff fabric, some with a dark-grey core. A
small proportion (15 fragments, 127g) occurs in a harder-fired, orange fabric. The
fragments display no evidence of deliberate ‘tempering’, although sparse limestone
inclusions were present amongst the material recorded from pit 10041 (fill 10043).
None of the fragments display any features that might indicate an original form and
function.
Metalwork by Katie Marsden
6.30 A total of three metal objects, two of iron and one probably of copper alloy, was
recorded from deposit 10041 (fill 10043). The metalwork has been recorded to an
Access database, and identifications are summarised in Table 2, below. The
assemblage has been examined by a specialist conservator (Karen Barker), and
items were subjected to x-radiography (X-ray plate K16/232).
![Page 55: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/55.jpg)

6.31 The extent of corrosion is variable. The ironwork, while characterised by heavy
corrosion, is not consistently fragmented, with the knife being complete and the bar
broken at each end. All items are currently stored in sealable plastic boxes with
desiccating silica gel, and are considered to be stable.
Range and Variety
6.32 All three items of metalwork were recorded from pit fill 10043, a deposit which also
contained worked bone weaving combs Ra. 5 and Ra. 6, together with quantities of
pottery dateable to the Middle Iron Age, Period 2. The concentration of ‘special’ finds
within this context suggests a structured deposit. This is discussed further in Section
8.6, below.

6.33 The iron knife is small, measuring 87mm in length. Its form compares to that of
Manning’s type 11, with its blade-back continuing in line from the handle, and is
more or less straight (Manning 1985). Knives comparable in form, although larger,
are known from Danebury (Sellwood 1984, fig. 7.10, nos. 2.28-30), from Middle or
Later Iron Age contexts.
6.34 The iron bar is rectangular in section and form, with a curve to one end. The bar is
broken at both ends, thus rendering difficult any formal identification of original form
and function.
6.35 The function of the probable copper alloy object is uncertain. It comprises a circular-
sectioned tube, measuring c. 20mm in length, with one enclosed end. The enclosed
end features decoration as a moulded ring and dot design (one dot enclosed by two
concentric rings). Preliminary assessments have been unable to identify convincing
Iron Age parallels, although a decorative use, perhaps an end-cap for a tool or
implement, is most likely.

Items of Worked Bone by Katie Marsden & E. R. McSloy
6.36 A total of two items of worked bone (Ra. 5 and Ra. 6) were recorded from pit 10041
(fill 10043). Identifications are summarised in Table 3, below. Both recorded items
are fragmentary, and Ra. 6 is also burnt and distorted. The surfaces of Ra. 5
appear weathered, probably as a result of the burial environment. Both worked
bone items are identifiable as weaving combs of a well-known Iron Age type, and
share characteristics of form and decoration with those from the sizeable Iron Age
Danebury group (Sellwood 1984; Cunliffe and Poole 1991). Plain/simple combs of
the kind represented by no. 1 made up approximately one third of those from the
Danebury Group (Selwood 1984, 372). The square/expanded butt form of no. 3 was
also well represented, and there are indications that this is a feature of Late Middle
or Late Iron Age combs (Cunliffe and Poole 1991, 357).
6.37 Such items were typically made from cattle or horse long-bones, although the
condition of Ra. 5 and Ra. 6 precludes identification of bone to species. Incised
decoration similar to that of Ra. 6 also occurs within the Danebury Group (ibid, fig.
7.229, no. 3.37), and with an example from Meare, Somerset (Coles 1987).

7. THE BIOLOGICAL RECORD
7.1 All ecofacts recovered from the excavation have been cleaned, marked, quantified
and catalogued by context. A total of 7 bulk samples were taken for the recovery of
environmental remains. The biological record is quantified in Table 4, below;

Animal bone by Matilda Holmes
Introduction
7.2 A small assemblage of animal bone was recovered from Areas 1, 2 and 3 of the
Cadnam Farm site, spanning the Middle Iron Age to Early Roman periods. The
sample was too small for detailed analysis, although some comments can be made
regarding the taxa present. The results of the animal bone assessment are
presented in Tables 10 and 11, Appendix E, of this report.
Methodology
7.3 Bones were identified using the author’s reference collection. Due to anatomical
similarities between sheep and goat, bones of this type were assigned to the
category ‘sheep/goat’, unless a definite identification (Zeder and Lapham 2010;
Zeder and Pilaar 2010) could be made. Bones that could not be identified to species
were, where possible, categorised according to the relative size of the animal
represented (small – cat/ rabbit sized; medium – sheep/ pig/ dog size; or large –
cattle/ horse size). Ribs were identified to size category where the head was
present, vertebrae were recorded when the vertebral body was present, and maxilla,
zygomatic arch and occipital areas of the skull were identified from skull fragments.
7.4 Tooth wear and eruption were recorded using guidelines from Grant (1982) and
Payne (1973), as were bone fusion, metrical data (von den Driesch 1976), anatomy,
side, zone (Serjeantson 1996) and any evidence of pathological changes, butchery
(Lauwerier 1988; Sykes 2007) and working. The condition of bones was noted on a
scale of 0-5, where 0 is fresh bone and 5, the bone is falling apart (Lyman 1994:
![Page 58: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/58.jpg)

355). Other taphonomic factors were also recorded, including the incidence of
burning, gnawing, recent breakage and refitted fragments. All fragments were
recorded, although articulated or associated fragments were entered as a count of 1,
so they did not bias the relative frequency of species present. Details of associated
bone groups were recorded in a separate table.
7.5 No sieved samples were available at this stage, which may lead to a negative bias in
the number and variety of small mammals, fish and bird bones recorded in the
assemblage.
Taphonomy and Condition
7.6 Bones were generally in fair to poor condition, with a high incidence of breakage
(Table 10, Appendix E), the proportion of fresh breaks and refitted fragments
indicating that burial conditions were not conducive to good preservation. The
presence of a number of teeth remaining in the mandible, in addition to refitted
fragments, further suggested that there had been little post-depositional disturbance.
A few butchered and burnt bones reflect the processing of bones, and some gnawed
fragments indicate that they were not always buried immediately after disposal, but
were available for dogs to chew.
A number of calcined bone fragments were recovered from Middle Iron Age (cxts
10045 and 10075) and late Iron Age-early Roman (cxt 30043) features.
The Assemblage
7.7 Because of the small sample size, there was little value in conducting a detailed
analysis of the assemblage. Sheep/goat remains were most common in both phases
(Table 11, Appendix E), although cattle and equids were also recovered in relatively
high numbers. Occasional finds of pig, canid and red deer were also made. Red
deer was represented by an antler tine, which may have been collected from shed
antler, and therefore not necessarily implying hunting activity. The majority of bones
came from head and upper limb bones, which suggests a bias towards meat-bearing
parts of the carcase, although the sample is too small to be definite. Neonatal and
very young sheep were evident from the mid-late Iron Age assemblage, indicating
that they were bred nearby, and the tibia of a juvenile horse, of between two and
four years of age, was also recovered.

Plant Macrofossils and Molluscs by Sarah Wyles
7.8 The charred plant remains from a total of seven bulk soil samples were analysed
from a range of features of Period 2 Middle-Late Iron Age date in Areas 1 and 3.
Four samples were taken from 10041 in Area 1, and three samples from ditches in
Area 3. The mollusc assemblages from these samples were also examined.
7.9 The bulk samples were processed following standard flotation methods, using a
250µm sieve for the recovery of the flot, and a 1mm sieve for the collection of the
residue. All identifiable charred plant remains were identified following the
nomenclature of Stace (1997) for wild plants, and traditional nomenclature, as
provided by Zohary et alet. al (2012), for cereals. The results are recorded in Table
12, Appendix E.
7.10 The nomenclature for the mollusc assemblages follows Anderson (2005), and
details of the ecological preferences of the species follow Evans (1972), Kerney
(1999) and Davies (2008). The results are recorded in Table 13, Appendix E.
Charred Plant Remains by Sarah Wyles
7.11 The charred plant assemblages from fill 10043 (samples 1 and 2), of pit 10041, were
dominated by weed seeds, while cereal remains outnumbered weed seeds in the
smaller assemblages associated with pots Ra 3 and Ra 4, from fill 10043 (samples 6
and 7) of pit 10041.
7.12 The cereal remains were predominantly grains of barley (Hordeum vulgare), with
some hulled wheat, emmer or spelt (Triticum dicoccum/spelta) grains, within the
assemblages. A number of the hulled wheat grains were identifiable as being those
of spelt wheat (Triticum spelta). No chaff elements were recorded.
7.13 The weed seed assemblages included seeds of medick (Medicago sp.), clover
(Trifolium sp.), cleavers (Galium aparine), meadow grass/cat’s-tails (Poa/Phleum
sp.), docks (Rumex sp.), vetch/wild pea (Vicia/Lathyrus sp.), field madder (Sherardia
arvensis), oats (Avena sp.), brome grass (Bromus sp.) and scentless mayweed
(Tripleurospermum inodorum).
7.14 These assemblages, with the presence of both the larger seeded/seed head, and
smaller-seeded, weed species, appear likely to be representative of debris from an
earlier stage of crop processing, namely the stage at which the crops are harvested,
threshed and winnowed, and coarse and fine-sieved in preparation for drying, prior
to storage as semi-cleaned grain or spikelets (Hillman 1981, 1984).
![Page 60: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/60.jpg)

7.15 The assemblages, particularly those from around Ra 3 and Ra 4, contained
quantities of vitrified material. This material appears to have formed under conditions
of high heat, and contained a number of plant stem impressions. It is thought that
this material probably comprises the remains of birch bark tar.
7.16 The moderate assemblage recovered from ditch 30140 (sample 4) was dominated
by barley grains, with a few grains of hulled wheat and seeds of clover/medick. No
chaff elements were present. A single barley grain was recorded from ditch 30137
(sample 3), and no plant remains from ditch 30126 (sample 5). The assemblage
from ditch 30140 may be representative of cleaned grain.
7.17 Spelt wheat is the dominant wheat species during the Middle-Late Iron Age period in
this part of the British Isles (Greig 1991), and is recorded, together with barley, from
a number of other deposits of Iron Age date within the wider area, including the
major assemblages at Danebury (Jones and Nye 1991), and smaller assemblages
from Danebury Road, Hatch Warren (Letts 2005), Brighton Hill South (Fasham et. al
1995) and Viables Farm Basingstoke (Millett and Russell 1984).
7.18 The weed seed species are typical of grassland, field margins and arable
environments. The majority of the weed seed species present are those favouring
drier, calcareous soils, such as field madder, clover, medick, corn gromwell
(Lithospermum arvensis) and ribwort plantain (Plantago lanceolata). The few seeds
of mallow (Malva sp.), from pit 10041, are indicative of the presence of some
damper environments in the vicinity. The presence of low-growing species, such as
clover and medick, within the weed assemblages may suggest a low harvesting
height by sickle (Hillman 1981).
7.19 Birch bark tar has been confirmed in use as a glue on repaired pottery sherds from a
number of Iron Age and Roman sites (Seager Smith forthcoming), although there
was no evidence of any residue on the pottery recovered from this site. Fragments
of birch tar were recovered from an Iron Age pit at Carshalton (ibid.), and the
charred plant assemblages from this pit also included smaller, seeded weed species
and barley grains (Wyles forthcoming), as was the case at Cadnam Farm. At
Carshalton, a number of the pottery sherds also showed glue repairs (Seager Smith
forthcoming).
7.20 Birch bark tar is formed by heating birch bark fragments to temperatures in excess
of 300-400˚C (Seager Smith et. al 2011, 125), and this may account for the very
high levels of vitrification observed in the charcoal assemblages from this site (see
![Page 61: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/61.jpg)

Challinor, this report). Birch wood may not have been used as the fuel, but if bark
was being removed from the tree for tar extraction, it may have been done in a
sustainable way, rather than felling the tree (Challinor pers. comm).
7.21 It is possible that the probable birch tar fragments were dumped as old, or spoilt,
material, along with domestic waste. The charred plant assemblages from pit 10041
were better preserved than the charcoal, and did not show the same signs of high
vitrification. They are therefore unlikely to be directly associated with the probable
birch tar fragments.
Summary
7.22 The cereal remains are compatible with the Middle-Late Iron Age date of the pottery
assemblages, and these remains may be indicative of an early stage of crop
processing taking place nearby. The weed seeds are typical of grassland, field
margins and arable environments. The presence of probable birch tar fragments in
some of the samples is noteworthy.
Mollusc Remains by Sarah Wyles
7.23 High numbers of mollusc shells were recovered from fill 10043 (samples 1 and 2) of
pit 10043, and small numbers associated with pots Ra. 3 and Ra. 4 from the same
pit. The assemblages were dominated by shells of the open-country species group,
including Helicella itala, Vallonia costata, Vallonia excentrica and Pupilla muscorum,
and the intermediate species Trochulus hispidus. These assemblages may be
indicative of a well-established, open landscape, with both arable environments and
pasture in the vicinity. The local pasture element may have comprised short-turved
grassland. Small assemblages, with a similar composition, were recorded from
ditches 30137 (sample 4) and 30140 (sample 4) in Area 3.
7.24 The large assemblage recovered from ditch 30126 (sample 5) was different in
composition to the other samples. In this case, the shells of the shade-loving
species were predominant, representing over half of the assemblage, and included
those of Discus rotundatus, Carychium tridentatum, Aegopinella pura and
Aegopinella nitidula. There were also a large number of shells of the intermediate
species Trochulus hispidus. The open-country species only formed 14% of this
assemblage. Although this ditch was probably situated within a generally well-
established, open landscape, there are indications, from the shade-loving element,
of the existence of larger-scale, shady environments within the vicinity of the Site,
rather than simply niche micro-environments within the ditch itself. Discus

rotundatus is a species which favours leaf-litter and the underside of logs within
woodland and hedgerow environments, while Carychium tridentatum, Aegopinella
nitidula and Aegopinella pura are all found in leaf-litter and in long, ungrazed
grassland. The assemblage may therefore be indicative of the presence of long,
unkempt grass, and possibly a hedgerow, near the ditch. There are no species
exclusive to woodland within the assemblage.
Summary
7.25 The mollusc assemblages are indicative of a well-established, open landscape, with
both arable environments and pasture within the vicinity of the Site. The pasture
element may have comprised short-turfed grassland, and there appears to be some
indication of long, unkempt grass, and a hedgerow, near ditch 30126.
Wood Charcoal by Dana Challinor
7.26 Six samples from Period 2, Middle to Late Iron Age features were submitted for the
examination of charcoal. Four of the samples came from a single pit, 10041, in Area
1, and two from Area 3 ditches 30137 and 30140. The material was extremely
sparse, with only a few small fragments present in most samples. All identifiable
charcoal was examined, with the exception of two richer samples (3 & 6), from which
a representative sample was examined. Standard identification procedures were
followed, using identification keys (Hather 2000, Schweingruber 1990), and modern
reference material. The limited results of the charcoal assessment are summarised
in Table 5, below.
7.27 The condition of the charcoal was poor, with very high levels of vitrification, making it
difficult to observe anatomical characteristics. Only one sample, from ditch 30137,
produced a reasonable assemblage. This comprised comminuted slivers of Quercus
sp. (oak), with some sapwood and roundwood noted. The other taxon positively
identified was Prunus sp. (blackthorn/cherry), from the fills of pit 10043. This was
probably P. spinosa (blackthorn), as it appeared to have large rays in transverse
section, but it was not possible to confirm this in longitudinal sections. The non-oak
charcoal originated from roundwood of small diameter. Traces of other non-oak taxa
were recorded, but could not be confidently identified (Table 5).

7.28 Despite the large quantities of charred material in pit 10041, there was little
preserved wood charcoal, and no identifiable bark fragments. If the charred material
does represent birch tar (see Wyles, this report, for discussion), the charcoal may
have derived from fuel waste from the process of heating the bark to extract the tar.
However, there were no identifications of birch wood or bark, and it is possible that
the charcoal entered the pit with a dump of general domestic fuel waste, along with
the burnt cereal remains. The rich assemblage from ditch 30137 is also likely to
represent a deliberate dump of waste fuelwood. The paucity of charcoal at the site
prohibits further interpretation, except to say that oak would have been common and
was clearly utilised for fuel in the Iron Age, as seen at other local sites of this period,
including Danebury Hillfort (Poole 1984), and Dowd’s Farm (Pelling 2012).
8. DISCUSSION 8.1 The Cadnam Farm site appears to represent a newly-established area of scattered
Middle Iron Age occupation, comprising a small enclosed settlement, with centrally-
positioned house and ancillary features, together with areas of unenclosed
settlement and agricultural activity within the vicinity. Unlike many areas of the
Hampshire chalk-lands, the wider environs of this site are associated with only
limited evidence of Middle and Later Iron Age settlement, and this has been
summarised in Section 2.3, above. It is therefore difficult to consider the Cadnam
Farm evidence in a sub-regional context, as relatively little investigation has been
undertaken in this part of East Hampshire, and there are few local comparator sites.
Cunliffe (2005, 252-3) has stated that the Middle Iron Age settlement landscape
within central-southern Britain during this period was increasingly filled with farming
![Page 64: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/64.jpg)

settlements which were sited to optimise resources, and relate to central places. The
Honeybourne Down enclosure described in Section 2.3 may conceivably have
fulfilled the function of such a central place, although examples of contemporary
settlements within its hinterland, beyond the few identified, are notably scarce.
However, a wider regional conspectus reveals the Middle Iron Age as a period of
rapid agricultural and settlement expansion (Haslegrove et. al 2001, 29), not least
into previously unsettled and agriculturally less-favourable areas (see Haselgrove
1995, 80-7). Such movements may represent socially-directed migrations from
areas of increasing population pressures and possibly degraded downland soils (see
Cunliffe 1984, 31; 1995, 96). However, this interpretation may be qualified by the
small quantities of residual Early Iron Age pottery which were recovered from pit and
ditch fills within evaluation trenches 14, 16, 25 and 26, and may represent some
form of earlier Iron Age activity around the Cadnam Farm site. Significantly, the
evidence for Middle Iron Age occupation at Cadnam Farm does not appear to
extend beyond the end of Period 2, and may have been of limited duration, which,
on the basis of roundhouse evidence, possibly extended to no more than two or
three generations. However, the deposits of domestic waste and ironworking debris
in the fills of Period 3 ditches in Area 3 (sections 30123 and 30140 respectively),
suggest that occupation of this date is likely to have continued in the vicinity.
The Period 3 Ditches
8.2 The Period 3 linear ditches 301, 302 and 303 in Area 3 are problematic, in that it is
not possible to fully elucidate their form or function. Their location, within Fields 3
and 4 of the Site, precluded their identification by geophysical survey and hence any
further interpretation of their form. The photograph in Fig. 5 appears to show soil
colouration suggesting a right-angled, north-eastward return of Ditch 301, which
might suggest that these ditches represent a ditched enclosure, although the
excavator has confirmed that this is purely a photographic effect, and that Ditch 301
extended only as far as its northern terminal, as shown on Fig. 5. These features
have therefore been interpreted as the possible opening of a drove-way, a not
uncommon feature on the chalk-lands of south-central Britain, where such openings
appear to represent the entry, or collection, points of extensive trackway systems.
These are generally associated with the movement and handling of livestock, and
frequently comprise part of rectilinear field systems (see Lambrick and Robinson
2009, 84, 85, Fig. 3.19; 110, Fig. 4.12). These ditches comprise substantial features
(Fig. 5), whose form and layout suggest that they comprised part of a single
coherent scheme of landscape reorganisation following the end of Period 2
![Page 65: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/65.jpg)

occupation. In this case, it might be expected that traces of a ditched drove-way
might extend southward from these excavated features, although, surprisingly, these
were not identified within any of the surrounding evaluation trenches.
Evidence of Industrial Activity
8.3 Small quantities of metalworking debris were recovered from the Cadnam Farm
site, and principally from the ditch fills of Period 3 date in Area 3. The small
quantities of diagnostic material present indicated smithing activity, although it is
possible that other industrial activities may be represented, and the presence of
birch bark tar may be significant in this context. There is no evidence of iron
smelting activity on, or around, the site. It is possible that at least some of this
debris could be residual material of earlier Iron Age date, although evidence of
small-scale ironworking is a common aspect of Middle and Late Iron Age sites
within the region, and is well represented elsewhere (Cunliffe 2005, 495). However,
a number of broadly contemporary sites in Hampshire have produced no evidence
of ironworking, including those at Easton Lane and Winnall Down (Fasham 1985;
Fasham et. al, 1989), and Oram’s Arbour, Winchester (Qualmann et. al, 2004).
Limited evidence suggests that here, as elsewhere, ironworking may have been
undertaken on a small-scale, episodic basis, was and designed to meet domestic
needs, or as a form of diversification within a predominantly farming economy
(Hingley 1997).
Evidence of Roundhouse Structures
8.4 Enclosure 1.1 within Area 1, contained two concentric sections of gulley, which on
the basis of respective profiles and fills may be interpreted as an inner ring-gulley
(105) and outer drip-gulley (104), representing a circular-plan building of c. 12m
internal diameter (fig. 3). Area 2 was associated with two superimposed ring-gullies
of comparative diameter, representing Roundhouses 3 and 4, Fig.4), together with a
closely-adjacent gulley which, on the basis of form and profile, may represent a third
circular-plan building (Roundhouse 5). The limited extent of areas excavated
precludes further interpretation of the character of settlement, although geophysical
survey (Pre-Construct Geophysics 2015) failed to reveal any traces of these
features. It is therefore possible that a more extensive area of settlement features
may be associated with the eastern part of the site, between Areas 1 and 2, as
possibly suggested by the evidence of evaluation trenches in this area (CA 2015,
Fig. 2). On the basis of available evidence, the roundhouses in Area 2 may be of a
![Page 66: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/66.jpg)

date which is only broadly contemporary with that of the enclosed settlement in Area
1, and it is possible that these two areas represent successive phases of Period 2
occupation. The relationship between enclosed and unenclosed settlement appears
to have been fairly fluid in the later Middle Iron Age, and it is possible that
Roundhouse 1 may pre-date Enclosure 1.1 (see Bowden and McOmish 1987;
Lambrick and Robinson 2009, 130-31). Comparative regional evidence, including
that from Winnall Down, Hampshire (Fasham 1985), suggests that much open
settlement of this period developed with little reference to any earlier, enclosed
settlement. In addition, the regional Middle Iron Age record displays considerable
variety in terms of relationships between enclosed and unenclosed settlement and
the areas enclosed, including approaches adopted to enclosing ancillary features
such as pits, four-post structures etc (see Lambrick 2014, 135-6).
Evidence for smaller post-built structures
8.5 A small, post-built structure, of circular plan and c. 4-5m in internal diameter, was
situated to the north-west of Enclosure 1.1, in Area 1 (Roundhouse 2, Fig. 3). The
component post settings were all undated, although it can be reasonably inferred
that Roundhouse 2 was broadly contemporary with Enclosure 1.1, but may pre-date
Ditch 101 of the associated drove-way entrance. Within Area 3, Roundhouse 6 (Fig.
5) was of similar stake, or post-built type, and represented a small, approximately
circular-plan building of c. 6.5m in internal diameter. In both cases, the shallow
surviving depths of the post settings and the small internal dimensions of the
building, suggest that these were not substantial, domestic dwellings (Sharples
2010, 193, Fig. 4.4), and may have been relatively transient structures. Harding
(2009, 68) has observed that simple, post or stake-built roundhouses of this type
rarely attain the same proportions as those of more ‘traditional’ (i.e. ring-gulley)
construction, and that it is by no means certain that all such examples were roofed.
The small sizes of Roundhouses 2 and 6 on the Cadnam Farm site suggests an
alternative interpretation as livestock pens, or the ‘working areas’ associated with a
number of contemporary sites (Collard et. al, 2006; Harding 2009, 68; Cunliffe 2005,
271-3), although these examples are otherwise within the size-range of Iron Age
domestic structures recorded within the region (Lambrick and Robinson 2009, 141).
In this case, a domestic function could be inferred by the remains of a quern
recovered from the upper fill of post hole 30104, immediately adjacent to
Roundhouse 6. This item may represent a deliberately placed object which may
have been connected with the life of the house, and commemorate a particular
![Page 67: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/67.jpg)

event. The presence of two distinctive roundhouse types across the site may also
suggest different contemporary functions, or conversely, different phases of
occupation, with the smaller, post-built houses possibly pre-dating the larger ring-
gulley types.
8.6 The evidence in Area 2 appears to indicate that Gullies 205, 206, 202, 20052 and pit
20060 all comprised disconnected elements of a single ring-gulley, which would
originally have been a continuous feature representing the plan of a single house
(Roundhouse 3, Fig. 4). Similarly, ring gulley 204 and segmented gulley 20064
plausibly represent the plan of a later, partly superimposed roundhouse
(Roundhouse 4, Fig. 4), of closely comparable size. This evidence appears to be
complemented by the circular configurations of internal pits or post holes, which may
be interpreted as two respective rings of internal post supports. On the assumption
that Roundhouse 4 was a direct successor to Roundhouse 3, it is tempting to
speculate on the possible timescales involved. A number of commentators (Brϋck
1991, 149; Brossler and Allen 2004, Figs. 13 and 16) have suggested that the use-
life of a prehistoric roundhouse may have been coeval with the life of its principal
inhabitant, and such short lifespans may be evident in a number of excavated
examples, including at Reading Business Park (Barnes et. al 1997, Fig. 4.14), where
numerous superimposed roundhouse plans were recorded, without much evidence
for a lengthy period of occupation in each case. At the near-contemporary site of
Winklebury, Basingstoke (Smith 1977), a roundhouse appeared to have been
reconstructed on almost the same spot on at least three different occasions (cf.
Guilbert 1981, 301-2). This may qualify a body of evidence which otherwise
suggests that abandoned house sites may have been considered taboo, and not
subsequently built upon. Sharples (2010, 228) has suggested that there may have
been no direct succession between occupants and their descendants in such cases,
and that the reconstruction of a house on, or close to, the location of the original,
may simply signify a deliberate act of inheritance by a new generation, possibly
involving the re-use of the timbers of the original house. This could conceivably
involve an interval in occupation of a generation or more in some cases, although it
is not possible to refine any chronological relationship between Roundhouses 3 and
4.
Evidence for Structured Deposition
![Page 68: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/68.jpg)

8.7 Both evaluation and excavation stages provided possible evidence of structured
deposition. Two large post pits, 7903 and 7907, within evaluation trench 79, each
contained what appeared to be a specially-placed item within their fills. In the case
of post pit 7903, this included a bone comb within primary fill 7904, and in the case
of post pit 7907, the single fill, 7908, contained an almost complete pottery vessel of
Middle Iron Age date. During the excavation of Area 3, fragments of a sandstone
saddle quern (SF 1) were recovered from the top of the fill 30105, of post hole
30104, located immediately to the south-east of Roundhouse 6 (Fig. 5). It is possible
to interpret each of these as deliberately-placed items, whose deposition may mark
particular events. It is possible that the quern fragments relate to the
decommissioning or demolition of Roundhouse 6 (see Hill 1995, 100-1, 108; Bradley
2005, 114, 119). In view of any excavated surrounding context, the significance of
the items within the Trench 79 post pits can only be tentatively interpreted, although
it is possible that these commemorate similar circumstances relating to domestic
occupation in either Area 1 or Area 2.
8.8 Pit 10041 (fill 10043), was located within the north-eastern margins of Area 1, and
contained a relatively rich assemblage of partially-complete pots (Ra. 3 and Ra. 4),
together with an iron knife (Ra. 1), a metal bead (Ra. 2) and two items of worked
bone (Ra. 5 and Ra. 6). The dark, humic, charcoal-rich character of this fill suggests
a deposit of domestic waste, although the inclusion of a number of household
objects strongly suggests deliberate placement and a possible act of
commemoration. The essentially domestic character of these items, and that of the
deposit in which they were placed, certainly falls within the definition of structured
deposition described by Hill (1995, 39-40), in which certain exceptional items, in
addition to a differentiated sequence of fills of different character, may be readily
distinguished from deposits of mixed and relatively homogenous character. It is
possible to speculate on the possible relationship of pit 10041 to the occupation of
the adjacent Enclosure 1.1, and to specific events in the life of this settlement. In
observing the spatial relationships of such deposits to later prehistoric settlements
and houses, and their role in the commemoration of life-events or domestic practice,
Hill (1995, 88-9) has suggested that these are essentially of an infrequent, episodic
nature (cf. Sharples 2010, 236). Lambrick and Robinson (2009, 286) observe that
such deposits mark significant episodes of change, which in this case may mark the
death, or departure from the community, of a specific individual. Equally possible in
this context may be the closure or abandonment of the settlement itself (cf. Gerritsen
2003, 102-4; Bradley 2005, 79-80), which may only represent a single, short-lived
![Page 69: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/69.jpg)

phase of occupation which was coeval with the lifetime of its principal inhabitant
(Sharples 2010, 222-3). While fill 10043 contained no structural material, including
daub, its high charcoal content may partly represent the destruction of Roundhouse
1 (Brϋck 1999, 151-2).
Evidence for Farming Regimes
8.9 Conditions on the Cadnam Farm site were not particularly conducive to the survival
of organic remains, and only tentative conclusions can be drawn regarding the
nature of the Middle Iron Age farming economy. Limited samples of cereal grains
were dominated by barley, with some emmer or spelt wheat. This is broadly typical
for the period, although no other cultivated species were present. Significantly, none
of the seven samples taken contained any evidence of chaff or crop processing.
This may simply mean that the grain in question had been cleaned and, in the case
of pit 10041, was derived from purely domestic contexts, and that crop processing
may have taken place elsewhere on site. Wyles (this report) has suggested that
weed seed component of the samples obtained may be indicative of an early stage
of crop processing, which may have been undertaken prior to storage. None of the
pits investigated were of a size and profile which suggested an original use for
agricultural storage. The limited sample of poorly-preserved animal bone was
broadly typical of the period in terms of species composition, but possibly with a
slight preponderance of cattle. It is possible that this settlement was principally
pastoral in its economic outlook, and relied upon imports of cleaned and processed
grain from elsewhere, although this would be quite untypical of Hampshire Middle
Iron Age sites as whole. Significantly, Wyles (this report) has assessed the mollusc
assemblages from this site as representative of a well-established, open landscape,
with both arable cultivation and pasture land within the vicinity. This supports
interpretations of an integrated, mixed farming economy on the site during Period 2
(Cunliffe 2005, 418-19).
Two-post structures
8.10 The three excavation areas have provided evidence for a variety of post-built
structures, in addition to a number of circular-plan buildings (Roundhouses 1-6, Figs.
3-5). Four-post structures of conventional Iron Age type are recorded in Area 1 and
3, with a six-post structure recorded in the north-west corner of Area 3. These are
common features of late prehistoric sites across southern Britain (cf. Lambrick and
Robinson 2009, 97-101, 104-5; Cunliffe 2005, 411-12), where they are generally
![Page 70: Cadnam Farm, Alton, Hampshire · Ordnance Datum (AOD) in Fields 1 and 2, down to 126m AOD in the south-west corner of Field 1. 1.5 The British Geological Survey Mapping (BGS 2015,](https://reader034.fdocuments.in/reader034/viewer/2022042111/5e8bd782722007103d2af6a7/html5/thumbnails/70.jpg)

associated with aspects of food storage. There are also a number of what appear to
be paired post holes in Areas 1 and 3, which may also represent simple post-built
structures, Area 3 is associated with some seven examples, with paired post holes
of comparable dimensions and fills separated by distances of between one and two
metres. Such paired post holes are not commonly described in the excavation
literature for the period, but were originally interpreted by Bersu and others on an
ethnographic basis, i.e. as free-standing racks used for the drying of fodder or other
materials (Harding 1972, 37-8). This interpretation was tested experimentally at
Butser by Reynolds (Reynolds 1999, 156-62), but remains otherwise unconfirmed,
due not least to the large number of possible alternative interpretations, and a
general lack of supporting archaeological evidence.
9. STORAGE AND CURATION
9.1 The archive is currently held at the CA Andover office, while post-excavation work
proceeds. Upon completion of the project, and with the agreement of the legal
landowners, the site archive and artefactual collection will be deposited with the
Hampshire Cultural Trust (accession number: A2015.66), which has agreed in
principle to accept the complete archive upon completion of the project.
10. PUBLICATION
10.1 The results from the investigations at Cadnam Farm are of sub-regional significance,
and merit publication. The site is a locally-rare example of Middle Iron Age enclosed
and unenclosed settlement, and may be illustrative of a period of settlement
expansion and social formation within an otherwise sparsely inhabited area to the
north of the Wey valley. It contains evidence of a number of examples of circular-plan
houses of different modes of construction, together with other post-built structures.
Connected with these may be some interesting examples of structured deposition,
together with evidence of possible landscape change and reorganisation in the Late
Iron Age period. It is therefore proposed that a short excavation report is published
in due course, in the Hampshire county journal, Hampshire Studies.

APPENDIX F: OASIS REPORT FORM
PROJECT DETAILS
Project Name Cadnam Farm, Alton, Excavation
Short description
Area 1, within the north-east of the Site, contained a D-shaped enclosure of Middle Iron Age date, which contained the remains of a roundhouse, and was associated on its north-west side by a ditched drove-way. A number of associated features included rubbish pits, a four-post structure and a small post-built structure of circular plan. Pit 10041 in Area 1 produced a rich assemblage of finds from fill 10043, including bone weaving combs, pottery and items of metalwork, which possibly comprised a structured deposit.
Area 2 was situated on the north-east margins of the site, and contained the super-imposed foundation gullies of two roundhouses, with a probable third example situated slightly to the south-west. The roundhouses contained internal concentric post settings, and were of Middle Iron Age date. Area 3 was located close to the north-west boundary of the Site, and contained the remains of a circular-plan, post-built structure in its north-east corner, together with a four-post structure and associated post holes and pits, most of which were undated. A number of paired and single post holes, together with a six-post structure, were located within the north-west corner of Area 3, and a discrete cluster of post holes further to the south-east represented a further small structure of indeterminate plan. A number of these features were assigned a Middle Iron Age date on the basis of pottery. Two large boundary ditches extended into Area 3 from its south-west corner, and were interpreted as the funnelled entrance of a drove-way. A number of internal post holes may represent structures associated with livestock handling. Two phases of ditches were evident, but these were mostly of late Iron Age/Early Roman date.
