The fortifications span approximately 2.6 kilometers, featuring a mix of stone walls and earthen ramparts that overlook the Geumgang River. Built originally as Ungjinseong, the structure was later renamed Gongsanseong during the Joseon Dynasty. The site encompasses several historic pavilions, including Gongsan Pavilion and Imnyugak Pavilion.
