Tongwan City Site, Jingbian, Shaanxi 陕西靖边统万城遗址
The Tongwan City site lies at Hongdunjie in Jingbian County, Yulin, on the southern edge of the Mu Us sandy land. It was the capital of the Xia state founded by the Xiongnu leader Helian Bobo in the Sixteen Kingdoms period, and is the only Xiongnu capital left in China. The walls are rammed earth mixed with lime and sand, greyish white in colour – hence its other name, White City – and are studded at intervals with projecting bastions and platforms for close defence.
