Dadiwan culture

The Dadiwan culture was a Neolithic culture found primarily in Gansu and western Shaanxi, China. The culture takes its name from the earliest layer found at the type site at Dadiwan. The remains of millet and pigs were found in sites associated with the culture. The culture shared several similarities with the and Peiligang cultures.

The type site at Dadiwan was discovered at Qin'an County, Gansu and excavated from 1975 to 1984. Dadiwan was built on a mountain slope south of the Qingshui River near the Wei River. The oldest layer of the site is from the Dadiwan culture, the middle layer is from the Yangshao culture and the youngest layer is from the Longshan culture.

The foundation of a large building, measuring 290 m? and 420 m? when including the outer courtyard, was discovered at Dadiwan. The building, known as F901, is described by Chinese archaeologists as a communal meeting hall. The building was built on an elevated rammed earth foundation, which was then layered with burnt clay.
