Bezeklik Thousand Buddha Caves

The Bezeklik Thousand Buddha Caves is a complex of Buddhist cave grottos dating from the 5th to 14th century between the cities of Turpan and Shanshan at the north-east of the Taklamakan Desert near the ancient ruins of Gaochang in the Mutou Valley, a gorge in the Flaming Mountains, in the Xinjiang region of western China. They are high on the cliffs of the west Mutou Valley under the Flaming Mountains, and most of the surviving caves date from the West Uyghur kingdom around the 10th to 13th centuries.
