In the Khentii province of Mongolia, south of Avarga oil spa and on the north side of Aurag spa, lies an ancient city buried beneath the soil of Rasaan Dersen Ukhaa. This site, known as Aurag, is believed to have once been a sprawling metropolis. However, researchers assert that the name "Aurag" does not necessarily mean "giant" or "great," as previously thought. In fact, during the 13th century, Chinggis Khan required a storage facility for food and goods collected as taxes from the countries under his rule. It is believed that the royal palaces were subsequently constructed here, and the area was subsequently referred to as Aurag.
According to excavations, Aurag Palace served as the capital of the Mongolian khanate and the capital of Great Mongolia for over 30 years beginning in 1189. The city occupied an area of 4.5 square kilometers and was divided into four distinct sections: handicrafts, farming districts, idol temples, and palace buildings with special walls. Surprisingly, there was no surrounding wall encircling the city. The craft and farming quarter was situated in the eastern part of the settlement, while the idol temple, which was surrounded by double walls, was located behind the central part of the city and accessible via a special staircase. The church building's foundation measured 180 square meters, and the number of columns on the foundation exceeded 40. A 6-sided stone pillar was discovered in front of the dovjoon. The western part of the city was surrounded by special walls that were positioned in a single row from east to west.
The ancient city of Aurag was once a hub of activity and home to numerous people engaged in various activities. While it was not surrounded by a wall, the city was divided into distinct areas for different purposes, such as farming, crafting, and worship. The temple, with its double walls and numerous columns, was undoubtedly a significant religious site. As more research is conducted on the ruins of Aurag, we can expect to learn even more about the history and significance of this incredible ancient city.
