The Character and Structure of Khureet Dov, Mongolia, Xiongnu capital

Korea-Mongolia Scientific Excavation Research Group investigated Khureet Dov, Mongolia, which is presumed to be the capital palace site among the five Xiongnu capital cities, twice in 2019 and 2023. The five cities, located with regular intervals to the west of the Kherlen River, are presumed to have served the following functions respectively: Khureet Dov-the capital in the Xiongnu period, Tereljin Durvuljin-winter, Burkhyn Durvuljin-spring, Undur Dov-autumn, and Gua Dov-summer palace. The structure of the gates and walls of Khureet Dov is considered to have been constructed with a main gate featuring a two-story tiled roof, supported by wooden pillars erected on a foundation of slab stone, with small gates on both sides, and walls with tiled roofs on both sides were connected. The internal structure of the fortress includes a central building area and a western building area clustered together, while the eastern building area is slightly separated. Each building area was connected by east-west and north-south corridors. The absence of facilities associated with the upper structure and the absence of excavated tiles used for roofing in the central and western building areas support the hypothesis that they were shaping the ground with the horizontal embankment method before placing a ger(traditional Mongolian tent) on top and building a Woldae(月臺) around it. The tiles are piled up on both sides of the southern central corridor and stair site, which are presumed to be the main entrance facilities of the central building site, suggesting that there is a high probability that its structure was made of wooden constructions with roof tiles on top.
