The wall was built during the reign of the First Emperor of Qin Dynasty, in short duration. It was not built all at once, but rather to communicate to several walls that had already been constructed above as well as reinforce new areas so the building was extended for a period of about a thousand years.

Construction

For its construction required a large army of people was composed of people from various regions of China, including soldiers, farmers and artisans. It was launched from north to west and diligently began the incredible construction.

The Wall has a height ranging between seven and ten meters. Its base is about seven meters and its top six. The floors were paved with a mixture of stone and mortar, supported by tree trunks rollers arranged in several layers. The materials used are those available in the vicinity of the construction. Near Beijing limestone was used. Other sites used granite or fired brick. Basically, it was a long wall of clay and sand, covered with several brick walls. That made it very resistant to the impacts of siege weapons.

Parts of the wall most visited by tourists have been kept in good condition or have been repaired, but in many parts of the wall has been neglected, serving as a playground for residents or as a source of stones to rebuild houses streets.
