Inner City

Beijing's Inner city is also called Jingcheng ("capital city") or Dacheng ("big city"). The eastern and western sections were originally part of the Yuan city of Dadu, while the northern and southern sections were built during the early Ming dynasty in the Hongwu (1368–1398) and Yongle (1402–1424) eras. The walls were formed from rammed earth covered with rocks and a finishing layer of bricks on both the interior and exterior. The average height was 12 to 15 metres. The northern and southern sections, built in the early Ming dynasty, were thicker than the eastern and western sections, built during the Yuan dynasty (1271–1368). The thicker sections averaged 19 to 20 metres at the base and 16 metres at the top, with parapets at the top. The Inner city wall had nine gates and a tower at each corner. There were three sluice gates, 172 enemy sighting towers, and 11,038 battlements. Immediately outside the city walls were deep moats 30 to 60 metres in width.
