Yungang Grottoes

The Yungang Grottoes, formerly the Wuzhoushan Grottoes, are ancient Chinese Buddhist temple grottoes built during the Northern Wei dynasty near the city of Datong, then called Pingcheng, in the province of Shanxi. They are excellent examples of rock-cut architecture and one of the three most famous ancient Buddhist sculptural sites of China. The others are Longmen and Mogao.

The site is located about 16 km west of the city of Datong, in the valley of the Shi Li river at the base of the Wuzhou Shan mountains. They are an outstanding example of the Chinese stone carvings from the 5th and 6th centuries. There are 53 major caves, along with 51,000 niches housing the same number of Buddha statues.
