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 Xionites appear to be synonymous with the Huna peoples of classical/medieval India, and possibly also the Huns of European late antiquity. It is unclear whether the Xionites were connected to a people named in Ancient China as the "Xunyu" ("Hünyü" 獯鬻; Wade–Giles "Hsünyü"), Xianyun 猃狁 (Wade–Giles "Hsien-yün") and Xiongnu (匈奴 Wade–Giles "Hsiung-nu"). (While some sources use names such as Hunas, Huns and Xiongnu interchangeably, this remains controversial.)
