The Yulin Caves are a Buddhist cave temple complex in Guazhou County, Gansu Province, China. The site is located some 100 km east of the oasis town of Dunhuang and the Mogao Caves. It takes its name from the eponymous elm trees lining the Yulin River, which flows through the site and separates the two cliffs from which the caves have been excavated. The forty-two caves house some 250 polychrome statues and 4,200 square metres of wall paintings, dating from the Tang Dynasty to the Yuan Dynasty (7th to 14th centuries). The site was among the first in China to be designated for protection in 1961 as a Major National Historical and Cultural Site. In 2008 the Yulin Grottoes were submitted for future inscription on the UNESCO World Heritage List as part of the Chinese Section of the Silk Road.
