The site of Guge Kingdom Ruins is located in Zanda County, Ngari Prefecture, southwest China's Xizang Autonomous Region. The existing site is built along the mountain, consists of more than 440 houses, 870 caves, 58 fortresses, 28 pagodas and 2 underground tunnels, and covers 180,000 square meters.

The ancient Guge Kingdom was probably founded in the 10th century but it was abandoned by the end of the 17th century. Only the mud-and-rock structures remained, sheltering their relics and wall paintings from the elements.

The Guge Kingdom Ruins are among the first group of historical relics placed under state protection in China. Remains of the kingdom's main castle now lie atop a riverside mountain, covering 180,000 square meters.
