Seoul Mongchontoseong Earthen Fortification

Mongchon Toseong, located inside Olympic Park, is an earthen fortress of Baekje built by compacting mud to form walls, utilizing the natural terrain along a tributary of the Han River. Notably, traces of wooden palisades were discovered on the stepped northern wall, indicating that it was defended with wooden fences. The fortress was constructed in a layered structure of outer and inner walls using the hills extending from Namhansanseong. It is one of the major fortresses built during the Hanseong period (3rd–4th century) when Baekje established its ancient state, and is presumed to be the site of Hanam Wiryeseong, designated as a Historic Site. Heading toward Mongchon Toseong from Olympic Park's North Gate 2, you will find the Mongchon History Museum. This museum displays artifacts excavated during the excavation of Mongchon Toseong, offering a glimpse into the history of the fortress and the traces of Baekje culture.
