The Shijiahe culture (Chinese: ; pinyin: Shjih Wnhu) (2500-2000 BC) was a late Neolithic culture centered around the middle Yangtze River region in Hubei, China. It succeeded the Qujialing culture in the same region and inherited its unique artifact of painted spindle whorls. Pottery figurines and distinct jade worked with advanced techniques were also common to the culture. The remains of copper ore and artifacts were discovered in one Shijiahe settlement.The type site was discovered at Tianmen County, Hubei, China. The upper layer of the type site belonged to the Qujialing culture. The site at Shijiahe covered an area of around 1,200,000 m. The settlement was surrounded by a moat and rammed earth wall. The type site was likely a regional center.Shijiahe is one of the largest towns excavated so far, almost a perfect square, one kilometer on each side.
