Yongle Palace, established during the Yuan Dynasty, is China’s largest surviving and most complete group of Yuan Dynasty Taoist buildings, renowned as “an Oriental Art Treasure.” Its key highlight is the 286 square meter “Zhaoyuan Tu” mural, showcasing a grand and imposing view of the Taoist cosmos. The main image, Eight-Armed Miri Lu, is outlined with gold leaf, with the flowing robes evoking a sense of ethereal music. The pigments from a thousand years ago remain vibrant, representing the pinnacle of mural art. The painted beams and murals within the hall are seamlessly integrated, and the “Twenty-Eight Constellations” map on the roof of the Dragon and Tiger Hall was painted with mineral pigments, perfectly blending with the architectural structure, reflecting ancient people’s profound understanding of harmony between heaven and earth.
