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).
Noin-Ula burial site
Despite the aforementioned excavated Noin-Ula portrait indicating Mongoloid lineage of the Xiongnu, Euro-centric observers of Xiongnu culture and history try to place the Xiongnu people in a non-Mongoloid or non-Asian ancestry or descendancy. Among the most important artifacts from Noin-Ula are embroidered portrait images. These shed light on the ethnicity of the Xiongnu, albeit controversially. It has been claimed that the portraits depict Greco-Bactrians, or are Greek depictions of Scythian soldiers from the Black Sea. Such suggestions are far-fetched. There are several historical sources confirming the appearance of the Xiongnu. In 350 AD, for example, power in the South Xiongnu state of Chjao (Pin. "Zhao") was seized by a usurper, a Chinese named Shi Min, who ordered all the Xiongnu in the state exterminated; in the slaughter "many Chinese with prominent noses" died, suggesting the Xiongnu had "prominent noses" compared to those of the Chinese. In the famous Chinese bas-relief "Fight on the bridge" the mounted Xiongnu are shown with big noses. A skull analysis of Xiongnu burials made by G.F. Debets found a distinct Paleo-Siberian type of Asian facial appearance with "not a flat, but with not strongly protruding nose", somewhat similar to some North American Indians. This type is represented on the embroidery from Noin-Ula. What to the rest of the Chinese looked like a high nose, to the Europeans looked like a flat nose.
