This stunning hilltop fortress is a reminder of a time when Gongju (then called Ungjin) was Baekje’s capital. After entering through the grand stone Geumseoru West Gate, you can walk along the fortress' perimeter and on its wall. Along the way you'll pass numerous pavilions, including Gongbungnu and Gwangbongnu, rebuilt according to archaeological evidence of their original structures. The best views are in the northwest section overlooking the river. In the evening the fortress is lit by floodlights.
