This Uighar capital ruin founded in 751 is situated on east bank of the Orkhon River 15km northeast from Khotont Soum, Arkhangai Aimag. After Uighar’s victory over Turkic empire in 745, Peilo became a new king of Uighar. After his death his son Moyunchur became Uighar king. During his reign, Uighar experienced the most flourishing time of its history and established the capital, Ordubalik, in Orkhon river valley.

Although over 10 cities had been established during Uighar period, only two ruins of them (Ordubalik and Baibalik) were remained today. This city was a fortified castle and one of main trade centers in Central Asia where Silk Road passes through. Ordubalik and Karakorum had been controlling northern branch of the Silk Road for over 400 years. Study on this city ruins proved that there were a state house, a state ministry, a cottage industry, trade districts, a religious temple, a fortified castle, a horse shed and a military warehouse in the city which stretches southwardly over 25km.

Decorated royal house remains were found inside the fortress during the expedition. In front of the fortress, there were a garden, a temple worship surrounded by a fortress and steles devoted to Uighar king with an inscription in Uighar and Chinese script in front of the temple. Many building traces on western and northwestern section of the city are supposed to be establishments which have formerly been used for a trade and a handiwork. Ordubalik was a big city. But, it wasn’t existed more than 100 years. In 840s Kyrgizs from Yenisei River fired the city. Khar Balgas was not only listed as an important historical site under state protection in 2002 but also recognized as a “cultural landscape” of the UNESCO World Heritage in 1996.
