Datong 大同

http://en.wikipedia.org/wiki/Hanging_Temple

The Hengshan Hanging Temple (Hanging Monastery, Xuankong Temple, 懸空寺; Xuánkōng Sì), located about 60 km southeast of Datong, China, in the Shanxi province, is one of the world’s forgotten wonders. Clinging to a crag of Hengshan mountain, in apparent defiance of gravity, it consists of 40 rooms linked by a dizzying maze of passageways. The temple is said to have been built by a monk named Liao Ran during the late Northern Wei Dynasty (386-534) and restored in 1900. It was constructed by drilling holes into the cliffside into which the poles that hold up the temples are set. Interestingly, the temple is dedicated to not just one religion, but three, with Confucianism, Taoism, and Buddhism all practiced within the temple and represented in 78 statues and carvings throughout the temple. www.atlasobscura.com/places/hanging-temple-hengshan

Hengshan Mountain is located in Hunyuan County of Shanxi Province in northern China. The mountain is one of the most widely known of the five sacred taoist mountains in China - the Northern Mountain. The hike offers amazing views from the mount and primeval trees that are rumoured to be as much as one thousand years old, with a shocking truth about the coal industry effect in its valleys, remining a Moon environment.
