Wudang mountain (Wudang-san) is in Hubei province of China and it is an UNESCO World Heritage Site and an important Taoist sacred place. It has many Taoist monasteries and a Forbidden City/Palace on its highest peak. The main deity is the God of Zhenwu and the monks practice meditation, Chinese medicine and Chinese martial arts. There is a legend that says Tai Chi was created there by Zhang Sanfeng who got inspired by watching a fight between a crane and a snake.
Jackie Chan's 2010 movie Karate Kid was partly filmed on the Dragon Spring Lake, Nanyang Temple, The Purple Heaven Palace and the Golden Palace on the Heavenly Pillar Peak.
The Mountain and its tradition has inspired many other Chinese movies -- one of them "Crouching Tiger Hidden Dragon" -- of which some were filmed on locations there.
