Jinyang Ancient City Relic Site, Archaeological site in Jinyuan District, Taiyuan, China.

Jinyang Ancient City Relic Site covers about 20 square kilometres of farmland in Gucheng Ying village, Jinyuan district, Taiyuan. Its core is the walled city, with temple and tomb remains on the surrounding hillsides; the western hills hold the Tianlongshan grottoes, the Mengshan Great Buddha and the Longshan carvings.

Jinyang was founded by Dong Anyu, a retainer of Zhao Yang, before the state of Zhao was established, and served as its first capital until 386 BC. It later became a military stronghold and administrative seat, and in 979, after the Northern Han surrender, Emperor Taizong of Song ordered the city burned and flooded, destroying it.

The name Jinyang survives in the villages that grew on the ruins, such as Gucheng Ying, Jincheng and Luocheng, and in the nearby Jinci temple complex at the foot of the western hills. Excavations since the mid-20th century have uncovered stone carvings and stretches of the earthen city wall. The site is now farmland, worked around the remains.

The ruins lie in the open farmland around Gucheng Ying village, Jin Yuan district, about 20 km southwest of central Taiyuan; the excavated remains are scattered across fields rather than concentrated in one enclosure. Most of the visible monuments, such as the Tianlongshan grottoes, the Mengshan Buddha and the Jinci complex, sit on the western hills and at the foot of the slope, so plan transport between separate stops. Ground is uneven and largely unshaded.

The Dunhuang Mogao Cave 61 mural, painted under the Guiyijun governor Cao Yuanzhong in the Five Dynasties, shows the northern half of Taiyuan's walled city in its lower left corner. Though stylised, it records the rammed-earth wall courses, gate-tower style and brick facing of the gates, and only the north gate is drawn with a barbican.
