A temple located in Bukhan-san within the confine of Goyang City, Bongseong-am is a branch temple that belongs to Jogye-sa, the main temple of Jogye Order of Korean Buddhism. It was founded in 1713 (Year 39 of King Sukjong) by the head monk Seongneung. It was one of twelve temples built during the construction of Bukhansan-seong ( Fortress) under the reign of King Sukjong in order to house the Buddhist Army that were to guard the fortress. With initially twenty-five rooms, it was repaired in 1860 (Year 11 of King Cheoljong) until which point, according to the construction log recorded by Bodam, the temple accommodated a sizable number of Buddhist monks and was visited by many believers. No record of subsequent repairs or changes made to the temple exist at the moment, and currently remaining buildings include Daewung-jeon, Sansin-gak, and Yosa-chae. It also houses a tower containing the remains of the founding monk Seongneung who also served as the head monk of Bukhansan-seong.
