The west gate as seen from the citadel
Ordu-Baliq[dn 1] (meaning "city of the court", "city of the army"), also known as Mubalik and Karabalghasun, was the capital of the first Uyghur Khaganate. It was built on the site of the former Göktürk imperial capital, 27 km north-to-northwest of the later Mongol capital, Karakorum. Its ruins are known as Kharbalgas in Mongolian meaning "black city". They form part of the World Heritage Site Orkhon Valley Cultural Landscape.
Ordu-Baliq is in a grassy plain called the Talal-khain-dala steppe, on the western bank of the Orkhon River in the Khotont sum of the Arkhangai Province, Mongolia, 16 km northeast of the Khotont village, or 30 km north-to-northwest of Kharkhorin. The Orkhon emerges from the gorges of the Khangai Mountains and flows northward to meet the Tuul River (the current capital of Mongolia, Ulan Bator, is on its upper reaches).
A favorable micro-climate makes the location ideal for pasturage, and it lies along the most important east-west route across Mongolia. As a result, the Orkhon Valley was a center of habitation and important political and economic activity long before the birth of Genghis Khan who made it known to the wider world.
In 744, after the defeat of the last Göktürk Kaghan by the Uyghur-Qarluk-Basmyl alliance, the Uyghurs under Bayanchur Khan (Bayan Çor) established their imperial capital Ordu Baliq on the site of the old ördü ("nomadic capital"). Ordu-Baliq flourished until 840, when it was reduced to ruin by the invading Yenisey Kyrgyzes.
The capital occupied at least 32 square kilometers. The ruins of the palace or temple complex laying at coordinates — which include the 10-meter-high double clay walls,4 meters apart,14 watch towers, 8 on the Southern side and 6 on the Northern side, two main entrances, one on East side and other on West side, a 12-meter citadel in the southeast corner and a 14-meter-high stupa in the center — clearly indicate that Ordu Baliq or Urgin Balyq  was a large, affluent town.
The urban area may be divided into three main parts. The central part consisting of numerous buildings surrounded by a continuous wall forms the biggest part. Ruin of a large number of temples and houses are to be found to the south beyond the center. The Khan's residential palace, which was also ringed by walls on all sides, stood in the northeastern part of the town, where the Russian archaeologist Nikolay Yadrintsev discovered a green granite monument with a statue of a dragon perched at the top and bearing a runic inscription glorifying the khagans.
Ordu Baliq was a fully fortified commandry and commercial entrepot typical of the central points along the length of the Silk Road. The well-preserved remains now consist of concentric fortified walls and lookout towers, stables, military and commercial stores, and administrative buildings. There are remains of a water drainage system. Archaeologists established that certain areas were allotted for trade and handcrafts, while in the center of the town were palaces and temples, including a monastery. The palace had fortified walls around it and two main gates, north and south, as well as moats filled with water and watchtowers.
The architectural style and planning of the city appear to have close parallels with T'ang Chinese models, although there are elements that appear to have derived inspiration from elsewhere.
An ambassador from the Samanid Empire, Tamim ibn Bahr, visited Ordu Baliq in 821 CE and left the only written account of the city. He traveled through uninhabited steppes until arriving in the vicinity of the Uighur capital. He described Ordu-Baliq as a great town, "rich in agriculture and surrounded by rustaqs (villages) full of cultivation lying close together. The town had twelve iron gates of huge size. The town was populous and thickly crowded and had markets and various trades." He reported that amongst the townspeople, Manichaeism prevailed.
He says that from (a distance of) five farsakhs before he arrived in the town (of the khaqan) he caught sight of a tent belonging to the king, (made) of gold. (It stands) on the flat top (sath) of his castle and can hold (tasa') 100 men.— Tamim b. Bahr al-Muttawwi'i, translation by Minorsky
The golden tent was considered the heart of the Uyghur power, gold being the symbol of imperial rule. The presence of a golden tent is confirmed in Chinese historical accounts where the Kirghiz khan was said to have vowed to seize the Uyghurs' golden tent.
In 1871, the Russian traveler Paderin was the first European to visit the ruins of the Uighur capital. Only the wall and a tower were in existence, while the streets and ruins outside the wall could be seen at a distance. He was told that the Mongols call it either Kara Balghasun ("black city") or khara-kherem ("black wall"). Paderin's belief that this was the old Mongol capital Karakorum has been shown to be incorrect.
The site was identified as a ruined Uyghur capital by the expedition of Nikolay Yadrintsev in 1889 and two expeditions of the Helsingfors Ugro-Finnish society (1890), followed by that of the Russian Academy of Sciences, under Friedrich Wilhelm Radloff (1891).
