Black Tiger Buddha-Hall is located in the southwest of One-Pine Pavilion, adjacent to Purple Bamboo Forest. It is one of the 72 water rooms in South Wutai. It is said that the ancient Black Tiger Buddha-Hall was founded in the Sui and Tang Dynasties. The hall enshrines Guanyin Goddess of Mercy and the protector of a black tiger is next to the Bodhisattva. It is the reason why this hall got its name. One oriental arborvitae grows in the courtyard, which is over 1,000 years old and is the tree under level 1 national protection.
