Dunhuang

Dunhuang is a city in China's northwestern Gansu Province, on the edge of the Gobi Desert. Once a frontier garrison on the Silk Road, it's known today for the Mogao Caves, a complex of 492 grottoes adorned with Buddhist statuary and frescoes. Carved into the cliffs above the Dachuan River, the caves were created between the 4th and the 14th centuries.
