About 풍납토성
Pungnaptoseong is a flat earthen wall built at the edge of the Han River in modern-day Pungnap-dong, Songpa-gu, Seoul, South Korea. It has a circumference of 3.5 km. It used to be included in the neighboring city of Gwangju. It has a long oval shape, spreading to north and south, and leaning slightly toward the east. Based on research conducted during the Japanese occupation, it has been speculated that Pungnap Toseong was Hanam Wiryeseong, the first capital of Baekje.
