Pungnaptoseong

Pungnaptoseong is an ancient fortress whose walls extend for several kilometers along a river and are built from compacted earth mixed with sand and stone materials. The structure demonstrates how people from this period constructed large-scale defensive works.

The fortress was built as part of an early kingdom's capital and served as a key defense against invaders. After several centuries of use, it was destroyed by external forces and eventually abandoned.

The name reflects the local area where the Baekje people built their settlement and carried out daily activities. Visitors can observe how the fortification was integrated into the community and what the layout reveals about life during that period.

Visitors can walk along the preserved earthen walls and examine the ancient construction methods up close. It helps to wear comfortable shoes since the paths traverse uneven terrain.

The walls were constructed using a sophisticated layering technique where sand and pebbles were compacted and capped with smooth stone. This building method was advanced for its time and allowed the structures to remain stable for centuries.
