Janggyeongsa-sinji Outwork

This defensive structure, called an Ongseong, is an outwork designed to defend a fortress gate or the curtain wall of a fortress. There are five such facilities along the walls of Namhansanseong, each of which is further fortified by a battery at its end. The Janggyeongsa-sinji Outwork is 159 meters in length, and has forty merlons and a pair of batteries at the end, with the embrasures opened towards the summit of Hanbong and the adjacent peaks. The left wall contains a facility called an Ebang, which is a storage compartment or space for weapons and gunpowder. The facility was built after the occupation of Hanbong Peak by Manchu forces during the Byeongjahoran (Second Manchu Invasion of Korea). The facility was restored after the excavation carried out in 2000 by a tea from the Land and Housing Museum.
