Which dynasty built most of the surviving sections of the Great Wall of China?

The Ming dynasty built most of the surviving sections of the Great Wall of China.

The Ming dynasty ruled China from 1368 to 1644 and invested heavily in defensive walls after conflicts with northern peoples, especially Mongol groups. Ming builders used bricks and stone extensively, which helped many sections survive and explains why visitors commonly associate the Great Wall with the Ming period.

The Great Wall was not one continuous structure built at one time. Earlier states and dynasties constructed separate fortifications, and the Qin dynasty connected some earlier walls after unifying China in the third century BCE. The Han dynasty also extended defenses along routes linked to the Silk Road.

The wall’s total length depends on what is counted, including trenches and natural barriers, but a major official survey measured more than 21,000 kilometres. The popular claim that it is visible from the Moon is false.
