Saseongam Hermitage (사성암)
Believed to have been constructed in 544 A.D. on the eastern frontier of the Kingdom of Baekje, Saseongam Hermitage remains today a must-see example of early Medieval Korean Buddhist architecture. Built on huge wooden pillars, the main buildings of the hermitage cling to the sheer cliffs of Mt. Osan in most dramatic fashion, overlooking the scenic Seomjin River far below. Originally named Osanam, in honor of the location, after stays by four preeminent monks—Wonhyo-daesa (617-686 A.D.), Uisang-daesa (625-702 A.D.), Doseon-guksa (827-898 A.D.), and Hyesim (1178-1234)—it was renamed Saseongam, literally “Four Sages Hermitage”. It remains an active hermitage today.
