A complex of 77 rock-cut Buddhist cave temples carved into a sandstone cliff above the Murtuk River valley, in the Flaming Mountains 50 km northeast of Turpan. The caves date from the 5th to 14th centuries; their frescoes — Buddhist iconography, Sogdian merchants, Uyghur royalty — were once among the finest in Central Asia.
Most of the best frescoes are gone, either chiselled out by foreign archaeologists a century ago or defaced by later religious iconoclasm. What remains is still affecting, and the setting at the rim of a narrow gorge is as dramatic as any in Xinjiang. Allow two hours plus driving time; usually combined with Gaochang and the Flaming Mountains.
