Yongle Palace is famous for its murals in the world. It is a treasure of existing mural art in China, comparable to Dunhuang murals. Yongle Palace is also one of the three major ancestral halls of Taoism in China. It was built in memory of Lv Dongbin, one of the "Eight Cave Immortals" of ancient Taoism in China.
Yongle Palace is huge, covering an area of127,000 square meters, with a building area of 86,880 square meters. The architectural feature of Yongle Palace is that five buildings, including Gongmen, Longhu Hall, Sanqing Hall, Chunyang Hall and Chongyang Hall, are arranged on a central axis from south to north. There are no affiliated halls and buildings on the east and west sides, but a long and narrow central courtyard with four walls. The three halls of Sanqing, Chunyang and Chongyang are concentrated in the second half and built on the platform. Other buildings were built outside the central courtyard, and another wall was built, which was orderly and formed its own unique architectural style.
Entering Yongle Palace, there are stone corridors on both sides of the courtyard. One imperial tablet is very valuable, and the words on other tablets are a little vague.
