Gansu grottoes showcase ancient murals

The Water Curtain Caves, famous for their grottoes and murals, are located at Luban Valley in Tianshui, Northwest China's Gansu province. The most impressive sight in the caves is a relief sculpture 42.3 meters in height.

The grottoes have been a feature of the area since the Qin Dynasty (221-206 BC), consisting of four clusters – Water Curtain Caves, Laqiao Temple, Thousand Buddha Caves and Xiansheng Temple.

Visitors can also view a variety of exquisite murals and painted sculptures dating back to the Northern Wei Dynasty (386-534).
