The Hanging Temple of Hengshan Mountain in Datong, Shanxi Province, was first built in 491 AD (the 15th year of the Taihe reign of the Northern Wei Dynasty) by disciples of the Taoist master Kou Qianzhi, based on his dying wish to "reach the heavens above and sever all worldly clamor below." With a history of over 1500 years, it is the oldest existing high-altitude wooden cliff-side architectural complex in China. **Structural Features:** 27 hemlock beams are inserted into the rock face as an "aerial foundation." The wooden pillars at the bottom are merely for psychological comfort; the actual load-bearing structure relies on hidden crossbeams, achieving the "suspended" appearance.
**Reasons for its excellent preservation:** The canyon terrain reduces sunlight erosion, the mountain shelters it from floods, and the mortise and tenon structure provides strong earthquake resistance.
**Cultural significance:** One of the world's ten most dangerous architectural wonders, and the only temple where Buddhism, Taoism, and Confucianism coexist, reflecting the inclusiveness of diverse ancient beliefs.
**Admission is free for those over 60, but tickets are extremely difficult to obtain during peak season; remember to book your visit in advance.**
