Coordinates: 37°59′51″N 108°51′46″E / 37.997515°N 108.862839°E / 37.997515; 108.862839 Tongwancheng (Chinese: 統萬城; pinyin: Tǒngwànchéng) was the capital city of the Southern Xiongnu, the only city of the Xiongnu that has ever been found. The city is well preserved and is located in Jingbian County, Shaanxi Province, China, close to Inner Mongolia. The city is at the southern edge of the Maowusu Sands of the Ordos Desert, on what was formerly a strategic site in the centre of the Ordos plateau. The city has been surveyed and some elements restored, but not yet excavated.

The city was built by around 100,000 Xiongnu of the Xia dynasty under the command of Helian Bobo (aka: He lian bo bo, Liu Bobo, or Helianbo) in A.D. 419, the Xiongnu having founded their steppe empire in the 3rd century B.C. Helian Bobo died in A.D. 425, and Helian Chang succeeded him as ruler of the city.

The Great Wall of China was built to contain the Xiongnu threat, and Tongwancheng was the main Xiongnu capital that stood on other side of that wall. The city was largely of wood construction and had very thick outer walls which were made white with white clay earth and powdered rice. From a distance the white city was said to have had the appearance of a giant ship. At its centre the city had a lake. Jin Shu gives us a contemporary eyewitness description of the city...

"The hill is beautiful, in front of it the plain is wide, and around this there is a lake of pure water. I have wandered in many places, but I have not seen a land whose beauty can compare with that of this place".

At its height the population was around 10,000, likely to have been greatly supplemented by an encircling encampment of nomadic kin groups at certain times of the year. White cities were generally ceremonial and status centres built following conquest, rather than outright military positions, white being a blessed colour for the Xiongnu. Yet the thickness of the walls was certainly required since the city was originally built at a time of perpetual warfare. The threat was also internal as well as from the Chinese - for instance, Helian Bobo was attacked with an army by his deputy Helian Gui in A.D. 424 following a dynastic dispute.

In A.D. 426, the Emperor Taiwu of Northern Wei made a surprise attack on Tongwancheng. Although a brief incursion into the city succeeded only in burning the main temple, the surrounding hinterland was devastated. The city's site was on the fertile upper reaches of the Wuding River, but the river and lake died up, possibly due to deforestation that might be traced back to Taiwu's devastation. The city was then gradually buried by the sands of the desert. This 'wandering' (Wuding) gave the river its current name.

The Xiongnu continued to live in the region until the 7th or 8th century. In A.D. 786 the city was besieged by Tibetan forces, and it was invaded by Jurchen soldiers in A.D. 1206. There is no record of the site in Chinese records after the early 1400s.

The city was found by Western explorers in the 19th century, but was only properly surveyed by the Chinese in the 2000s. The city's Yong'an Platform, a military forces inspection platform for dignitaries, has been restored.

The city is also referred to in the literature variously as Tong Wan Cheng, Tongwan-cheng, Baichengzi, Xia Zhou, Tongwan, or Bai Cheng (the latter meaning in the ancient Xiongnu language 'White City').
