Bashidang

Bashidang (simplified Chinese: 八十垱; traditional Chinese: 八十壋; pinyin: Bāshídàng) was the site of a Neolithic Yangtze River settlement in Lixian County, Hunan, China. Bashidang is considered to be a very late site of the Pengtoushan culture. The site is the earliest in China to feature both a wall and a ditch; the ditch was the outermost perimeter. A raised, star-shaped platform was found at the center of the settlement, possibly used for ceremonial purposes.
