The Mogao Caves, also known as the Thousand Buddha Grottoes or Caves of the Thousand Buddhas, form a system of 500 temples 25 km (16 mi) southeast of the center of Dunhuang, an oasis 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 as a collective term to include other Buddhist cave sites in and around the Dunhuang area, such as the Western Thousand Buddha Caves, Eastern Thousand Buddha Caves, Yulin Caves, and Five Temple Caves.
