The Mogao Caves, or Mogao Grottoes (also known as the Caves of the Thousand Buddhas and Dunhuang Caves) form a system of 492 temples 25km (15.5 miles) southeast of the center of Dunhuang, an oasis strategically located at a religious and cultural crossroads on the Silk Road, in Gansu province, China on the edges of the Taklamakan Desert. The caves contain some of the finest examples of Buddhist art spanning a period of 1,000 years.[1] Construction of the Buddhist cave shrines began in 366 CE as places to store scriptures and art.[2] The Mogao Caves are the best known of the Chinese Buddhist grottoes and, along with Longmen Grottoes and Yungang Grottoes, are one of the three famous ancient sculptural sites of China.
