Yongle Palace, located in Ruicheng County, northern Shanxi Province, is China's most well-preserved Yuan-Dynasty architecture. The scale and artistic achievement of its mural paintings are known as the top best among all existing mural paintings of the same subject. But many may not know that this magnificent Taoist temple structure was entirely moved from its former site in Yongle Town to Ruicheng County between 1959 and 1964. UNESCO's nomination process stipulates that moved historical buildings are not qualified for the World Heritage nomination, but Yongle Palace was included on the tentative World Cultural Heritage list in 1998. According to the senior expert from the World Heritage Center who visited Yongle Palace in 2005, the whole movement project was well-designed and conducted with superb skills, which retained integrity and authenticity of this historical building to the largest possible extent. Thus, it can be included on the tentative list as an exception. Yongle Palace, with its full name as "Dachunyang Longevity Palace", was first built in 1247 and completed in 1368. It is so named after the former site of the Palace, which is Yongle Town. The Palace, built in honor of Lu Dongbin, an ancestral master of Taoism, is known as the country's oldest, largest and most well-preserved Taoist temple. It is also generally recognized as one of the three main ancestral halls of Quanzhen Sect of Taoism. Yongle Palace covers an area of 86,000 square meters. On its 500-meter-long axis line stands four main halls whose walls are painted with exquisite murals totaling some 1000 square meters. Mural paintings in Sanqing Hall are considered the most beautiful. They cover an area of 400-odd square meters, with 4.26 meters in height and 94.68 meters in length. This group of mural paintings, completed in 1325, highlights the Taoist rite where Heavenly gods show respect for the Celestial King of Creation. 298 Heavenly gods line up symmetrically in four groups, looking dignified and solemn. These gods feature large sizes, with the main gods as tall as 2.85 meters and heavenly ladies as tall as 1.95 meters. Chunyang Hall was built to enshrine the statue of Lu Dongbin. The 52 sets of mural paintings within the hall, totaling 203 square meters, depicts the whole life of this ancestral master of Taoism.
