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
The Juqu were a branch of the Xiongnu. Their leader Juqu Mengxun took over the Northern Liang by overthrowing the former puppet ruler Duan Ye. By 439, the Juqu power was destroyed by the Northern Wei. Their remnants were then settled in the city of Gaochang before being destroyed by the Rouran.
