     The Yungang Grottoes (云冈石窟) lie on the north cliff of Wuzhou Mountain, Datong.

They occupy 1 km from east to west, and hold 53 caves and over 51,000 stone statues.

As excellent examples of rock-cut architecture(建筑学), in 2001, the Yungang Grottoes

became a UNESCO World Heritage Site. According to UNESCO, they are a masterpiece

of early Chinese Buddhist(佛教的) cave art. 

     During the Northern Wei Dynasty, Pingcheng, now called Datong, was made capital city,

and Buddhism was treated as state religion. Through the ancient North Silk Road, Buddhism

arrived in Pingcheng (Datong). The Yungang Grottoes absorbed Indian Buddhist art, and

combined with traditional Chinese art. They were China's first major stone carved grottoes,

and have a history of over 1,500 years. During the rule of Emperor Xiao Wen in Northern

Wei Dynasty (386-534), a monk named Tanyao was responsible for the construction of the

Yungang Grottoes. The most important work on the grottoes was completed during 460 to

the early 490s. The move of the Northern Wei capital from Pingcheng (Datong) to Luoyang

in 494 ended the construction and carving. Some repairs continued during the Sui and Tang

dynasties, and important restorations (修复) were carried out in the 11th and 12th centuries.

     The Yungang Grottoes include a variety of vivid religious figures. Moreover, there are a

lot of different shaped wooden constructions, statues of the Buddhist story, and carvings of

ancient musical instruments.
