The Beijing city wall was a series of fortifications built between the early 1400s and 1553. The Inner city wall was 24 km long and 15 meters high; with a thickness of 20 metres at ground level and 12 metres at the top. It had nine gates. This wall stood for nearly 530 years; but in 1965 it was removed to allow construction of the 2nd Ring Road and the Line 2; Beijing Subway.

Only one part of the wall is extant; in the southeast; just south of Beijing Railway Station. The Outer city walls had a perimeter of approximately 28 kilometres. The entire enclosure of the Inner and Outer cities had a perimeter of nearly 60 kilometres. Pictures From History William H Jackson
