Archaeological ruins of Liangzhu City

The archaeological ruins of Liangzhu City, or simply the Liangzhu site, are a cluster of Neolithic sites located in the Liangzhu Subdistrict and Pingyao Town of Yuhang, Hangzhou, China. Initially excavated by Shi Xingeng in 1936, the ruins were recognised to belong to a previously unknown civilisation, termed Liangzhu culture, in 1959. The site was confirmed as an ancient city after the discovery of its city walls in 2006.
