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).
Xionites
The defeat of the Xiongnu in 89 CE by Chinese forces at the Battle of Ikh Bayan and subsequent Chinese campaigns against them, led by Ban Chao may have been a factor in the ethnogenesis of the Xionites and their migration into Central Asia.
