Tianlongshan Grottoes, cut into a sandstone cliff in the mountains west of Taiyuan, contain Buddhist sculptures spanning from the Northern Qi dynasty (550–577 CE) to the Tang (618–907). The site comprises 25 numbered caves with carvings that display a clear stylistic evolution across the six centuries of their making — the Northern Qi figures are blocky and solemn, while the Tang figures achieve an extraordinary softness and naturalism particularly evident in bodhisattva figures.
Many of the most famous sculptures are no longer here — the site suffered major looting in the early 20th century, and the removed pieces now sit in major Western and Japanese museums. The remaining carvings still repay careful attention, and some of the cave interiors retain their original polychrome decoration. The mountain setting is also genuinely beautiful: a gorge walk approaches the caves through deciduous forest, and the views from the cliff top over the surrounding valley are worth the climb.
