This is a great opportunity to get a grip on Wǔdāng Shān history, lore and architecture. There’s a whole pantheon of gods, including the eminent Zhenwu (patriarch of the mountain) and a section on Taoist medicine including the fundamentals of nèidān Xué (内丹学; internal alchemy). There are also some stunning bronze pieces.
The museum is down Bowuguan Lu (博物馆路), which leads to Culture Sq (Wenhua Guangchang).
