The Qianling Mausoleum is a Tang Dynasty (618–907) tomb site located in Qian County, about 85 km northwest of Xi'an. It was built in 684 (with additional construction until 706), and the tombs of the mausoleum complex house the remains of various members of the royal Li family. This includes Emperor Gaozong of Tang (reigning from 649–83), as well as his wife, the Zhou Dynasty usurper and China's only governing female emperor Wu Zetian (r. 690–705). The mausoleum is renowned for its many Tang Dynasty stone statues located above ground and the mural paintings adorning the subterranean walls of the tombs. Besides the main tumulus mound and underground tomb of Gaozong and Wu Zetian, there is a total of 17 smaller attendant tombs or peizang mu. Presently, only five of these attendant tombs have been excavated by archaeologists.
