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
Both the 7th-century Chinese "History of the Northern Dynasties" and the "Book of Zhou", an inscription in the Sogdian language, report the Turks to be a subgroup of the Huns.
