Chengtoushan

Chengtoushan was a Neolithic settlement located on the northwestern edge of Dongting Lake in Lixian County, Changde, Hunan, China.

The site contains the earliest dated rice field in China . The settlement spanned three separate cultures: the Daxi culture, the Qujialing culture and the Shijiahe culture. The site was abandoned around the middle period of the Shijiahe culture.

Chengtoushan was a round settlement surrounded by a moat and rammed earth wall, which was first built during the Daxi culture. The remains of human sacrifices were discovered under the foundation of the wall. The remains of a gravel road, a river bridge and a river-control gate were also discovered at Chengtoushan.
