It contains the remains of several well organized Neolithic settlements dating from approximately 4500 BCE. It is a large area of 5-6 hectares and surrounded by a ditch, probably a defensive moat, five or six meters wide. The houses were circular, built of mud and wood with overhanging thatched roofs. They sat on low foundations. There appears to be communal burial areas.Banpo is the type-site associated with Yangshao Culture. Archaeological sites with similarities to the first phase at Banpo are considered to be part of the Banpo phase (5000 BC to 4000 BC) of the Yangshao culture. Banpo was excavated from 1954 to 1957 and covers an area of around 50,000 square metres.The settlement was surrounded by a moat, with the graves and pottery kilns located outside of the moat perimeter. Many of the houses were semisubterranean with the floor typically a meter below the ground surface. The houses were supported by timber poles and had steeply pitched thatched roofs.
