The Dongjing City was built in the sixth year of Tianming of Nuerhachi in the Posterior Jin Dynasty. The city had the shape of a diamond. It was as long as about 896 meters from the east to the west, and as wide as about 886 meters from the south to the north. The whole city covered an area of 0.75 square kilometers. In every rampart there were two city gates, and the city had 8 city gates altogether. There were two high points within the city. On the one point was the Octagon Dragon Palace; on the other was the Imperial Sleeping Palace. In the eastern part of the city was the Mituo Buddhist Temple. However, there remain today only the Tianyou Gate, some parts of the ramparts, the stone gate inscribed with Han and Man characters, and coloured glaze decorations.
In the tenth year of Tianming (1625AD), Nuerhachi moved the capital to Shenyang. At the same time, he set high-ranking officials to stay to take care of the Dongjing City, and troops also stationed in the city. In the 20th year of Kangxi (1681AD), the troops moved to Jinzhou city, and thus the Dongjing City got discarded slowed. The Dongjing City has only four years’ history as a capital. However, in the four years, Nuerhachi had carried out a series of political, economical, military and religious reforms in the Dongjing city. Under his guidance, the society of the Nuchen nationality changed greatly. The Dongjing City is of great importance in the history of architecture of the Qing Dynasty.
The Dongjing City was the capital city built more than 300 years ago in the seventh year of Tianming of the Posterior Jin (1622AD) when Nuerhachi, the founder of the Former Qing Dynasty, established the capital in Liaoyang. The enceinte was built on a high place facing the water on one side. it was built with stones and bricks. The city is 890 meters long from the east to the west, and 886 meters wide from the north to the south. The total length of the city walls is 3,510 meters. There are eight city gates altogether, with two in each of the four sides. You can still find the site of the Octagon Palace on the hillock in the northwest part of the city where Nuerhachi had discussed the government affairs. Most parts of the enceinte have collapsed for the lack of proper repair. Among the eight city gates, only the frontispiece in the south, the Tianyou Gate, remains. All the unearthed stele stones, plaques and the hangovers of the palaces have been kept in the Liaoyang Museum.
