Architecture of Mongolia
The Xiongnu confederation ruled present-day Mongolia from the third century BCE through the first century CE, living in portable, round tents on carts and round yurts. The Xiongnu aristocracy lived in small palaces, and their villages were protected by huge walls. S. I. Rudenko also mentions capital construction built of logs. Archaeological excavations indicate that the Xiongnu had towns; their chief city was Luut Hot (Dragon City).
Xiongnu
After their previous overlords, the Yuezhi, migrated into Central Asia during the 2nd century BC, the Xiongnu became a dominant power on the steppes of north-east Central Asia, centred on an area known later as Mongolia. The Xiongnu were also active in areas now part of Siberia, Inner Mongolia, Gansu and Xinjiang. Their relations with adjacent Chinese dynasties to the south east were complex, with repeated periods of conflict and intrigue, alternating with exchanges of tribute, trade, and marriage treaties.
