The city dates to 403 AD and was built by the Goguryeo people who occupied much of the Liaodong Peninsula, modern Jilin province, Northern Korean Peninsula and part of the Primorsky Krai in modern Russia. Yanzhou was a major city at the frontier between the Goguryeo and Tang dynasty China. In 642 AD, the Goguryeo had a war with the neighbouring land of Silla on the Korean Peninsula. The Silla appealed to the Tang Emperor for assistance and in 645, the Emperor Taizong attacked the Goguryeo. The Tang first captured nearby Liaodong City. Then in June, they attacked at Yanzhou led by Tang Jun and after fierce fighting and some notable heroics by the Emperor and his generals, won. Location 
The city was built on a ridge on the northern side of the Taizi River. (), approximately 20 km east of Liaoyang and 50 km south of Shenyang (). Construction 
As with other Goguryeo forts, Yanzhou village was built on a hill adjacent to a river, with the river forming a natural barrier. Cliffs form the southern side of the city and a high defensive wall formed an arch around the west, north and east sides. The land slopes such that the eastern side of the city is significantly higher than the west. The site is about 480 metres long and 440 metres wide. The city walls, which are still visible today, cover some 1840 metres in length. The walls were 2 to 3 metres thick and between 5 and 8 metres high with towers at regular intervals along its length, and is comparable to the Great Wall of China in its dimensions.

The construction is of rough-cut stone built dry without mortar. Status 
The city walls in Yanzhou are a protected site of Liaoning province.
