Sangwansa is a temple on Odaesan Mountain that was originally established as Jinyeowon in 705. Although the Joseon Dynasty's policy was the prohibition of Buddhism, it constantly donated to rebuild the temple. In 1401, King Taejong donated to the construction of Sajaam Hermitage. In 1465, King Sejo and administrators donated to rebuild the temple. Sejo's son, King Yejong designated it as a memorial for his father. During the Third Battle of Seoul, the United Nations Command ordered that the temple be burned, but a Buddhist monk prevented it. Instead, the Command agreed to burn only the doors of the temple.
