Gongju also has its very own fortress! Gongsanseong Fortress was built as a defensive facility for the royal palace (that sadly does not exist anymore). The total length of the fortress amounts for 2,660m (stone walls: 1,925m; earthen walls: 735m). After the downfall of Baekje, the fortress ramparts were reconstructed and rebuilt as stone walls.

Today, there are daily changing of the guards performances at the fortress at every full hour from 10 AM to 4 PM (except noon).
