Located on the foot of Dongnisan Mountain, Taeansa Temple was built by three monks during the reign of the Silla King, Gyeongdeok (742). Afterwards, Monk Hyecheol constructed a large temple with 132 rooms during Goryeo Taejo’s reign, which was established as a central seminary of the Dongnisan Mountain area. In the precincts there are four treasures, including Hyecheolguksa Sari Pagoda, Gwangjaseonsa Pagoda and Neungpagak. The temple was badly damaged during the Korean War and had been refurbished since then. An invigorating valley and a shady nook can be reached just 1.8 kilometers from the entrance of the temple. It is a popular trail during the fall, with its bright maple leaves.
