The Mogao Caves or Mogao Grottoes, also known as the Caves of the Thousand Buddhas, form a system of 492 temples 25 km southeast of the center of Dunhuang, an oasis strategically located at a religious and cultural crossroads on the Silk Road, in Gansu province, China. The caves may also be known as the Dunhuang Caves, however, this term is also used to include other Buddhist cave sites in the Dunhuang area, such as the Western Thousand Buddha Caves, and the Yulin Caves farther away.
