Pungnaptoseong: The Ancient Earthen Fortification of Baekje
Located along the banks of the Han River in modern-day Seoul, Pungnaptoseong stands as a testament to the early engineering and strategic planning of ancient Korea. This massive earthen wall, situated in Pungnap-dong, Songpa-gu, is widely believed to be the site of Wiryeseong, the first capital of the Baekje kingdom.
The site is characterized by its long oval shape, stretching north to south and leaning slightly toward the east. While it is now a central part of the metropolis, the fortification was historically associated with the neighboring city of Gwangju.

Architectural Design and Construction
The construction of Pungnaptoseong demonstrates a sophisticated approach to earthen fortifications. The structure consists of a central core and an inner wall designed for stability and defense.
Composition of the Walls
The inner wall was created by heaping earth at a slant, utilizing a mixture of sandy soil, grit, clayish soil, and muddy soil. To reinforce the structure, builders laid pebbles in three distinct layers on top of the final earthen layer.
Structural Dimensions
Inside the fortification, trimmed stones were piled up to a height of 1.5 meters using natural mud. The central part of the wall was constructed in a trapezoid shape, featuring a base width of 7 meters and a height of 5 meters.
Due to the passage of time and environmental factors, such as flooding that destroyed the west wall, only 2.7 km of the original walls remain today. However, the overall footprint continues to define the historical landscape of the region.
