Xin Lixiang, an archaeologist from China's National Museum who is also a scholar on Qin and Han dynasties, said that the Great Shangqing Palace was a place of worship for a line of emperors throughout Chinese history and was the primary location for the Zhengyi sect of Taoism.
Archaeologists have excavated 5,000 square meters of the palace, which was dedicated to a Chinese Taoist master, located at the foot of Longhu Mountain in east China's Jiangxi Province.
During Song Dynasty, a Taoist palace dedicated to Zhang was built at the foot of the mountain, and was later expanded and became an imperial palace for Taoist practice through Yuan Dynasty (1271-1368).
The palace was destroyed in a fire in 1930.

In 2014, workers building a scenic area at the mountain found a stele with characters marking a major renovation of the palace during the rein by Emperor Jiaqing (1760-1820) of the Qing Dynasty.
Archaeologists said it is the largest excavation of a Taoist site in China. In addition to the core palace excavation, archaeological surveys have been carried out over a 30 square km area to ascertain the original palace structure.
A trove of pottery and porcelain as well as building materials were unearthed, including glazed tiles from the temple's ancient paintings.
Archaeologists believe that the ruins of the palace are worthy of an application for world heritage classification in the future.
