Namhansanseong Fortress

A mountain fortress of the Joseon period built on the hills of Gwangju, Gyeonggi Province, using the rugged terrain as a defensive stronghold protecting the capital. It is famous as the place where King Injo took refuge and held out against the Qing army during the Byeongja War. The walls following the mountain terrain, Sueojangtae (command post), and a detached palace remain. A well-maintained fortress trail that winds through the mountain village is in place, and it is inscribed on the UNESCO World Heritage List.
