In the South Cliff View-site of the Wudang Mountains, the most famous architecture is a stone palace named the Tianyi Zhenqing Palace. It's said that after Zhenwu ascended to heaven, he lived in this palace. The Tianyi Zhenqing Palace was built by a famous Taoist Zhang-Shouqing at the beginning of the Yuan Dynasty and was finished 27 years later. Zhang went to Wudang Mountain at the age of 30 and led his thousands of disciples to reclaim wasteland, plant the land and cut the cliff and then left this marvelous spectacle for the later generations. This stone palace is the one of the masterpieces of Chinese ancient architecture and is a representative of ancient Chinese stone buildings. The Tianyi Zhenqing Palace is made of wood-like stones. The roof beams, pillars, square timbers, windows, doors, joints and decorations of animal sculptures on the roof ridges, were carved from green stones and then combined together. The whole palace, accurately designed, delicately structured, and exquisitely carved, is a masterpiece of the large Chinese stone carvings. The difficulties of building this palace on the steep cliff stretch our imagination to the limit. A 2.9m long stone beam resembling a dragon's head protrudes out over a cliff. It protrudes from the cliff-side temple passage and originally held a bronze incense burner. Legend said that placing incense here at dawn was a show of courage and an act of faith. with an incense burner at its end. Modern day visitors continue to be impressed by the ancient craftsmen who built this without any high-tech gadgets and worshippers test their faith by crawling onto the dragon's head to place their incense sticks, despite it being extremely dangerous. This Dragon-head Incense burner, an excellent stone scarved architectural art, points exactly to the Golden Summit of Wudangshan to the south.
