Official replies place Qianling in Qian County, Xianyang, as the joint tomb of Tang Gaozong Li Zhi and Empress Wu Zetian. Heritage releases add that the site set the pattern of building imperial tombs against mountains—a form later dynasties repeated along the Guanzhong ridge. Qianling National Archaeological Park is listed among open parks, while the Qin Xianyang city archaeological park remains only an approved project in the same inventory.

Two reigns, one hill
Gaozong and Wu Zetian share a Qian County tomb built into a mountain, with national policy still against opening the chamber.

A 2007 debate, not a fresh dig plan
A 2007 essay republished by the provincial gazetteer office records that national authorities did not support excavating Qianling and that the tomb would not be opened. The same piece describes the underground chamber area as still untouched by successful robbery. That dated argument is evidence of long-standing restraint—not a present engineering inspection—and it belongs beside the visible mountain seal rather than inside it.
