Situated in a dense forest in Sangwangsan Mountain and 6 kilometers away from Haemi-myeon, Gaesimsa Temple is one of the four major temples in Chungcheongnam-do. The path from the parking lot to the temple site is quite remote and curved, but beautiful especially in spring when cherry blossoms are in full bloom.

The temple was built in 1484 during the 15th year of King Seongjong and designated as a Treasure. The architecture of the temple stands out, as the buildings use bent tree trunks for pillars.
