Wiryeseong was the name of two early capitals of Baekje, one of the Three Kingdoms of Korea. Both are believed to have been in the modern-day Seoul area. According to Samguk Sagi (the oldest surviving Korean history book, written in the 12th century), Onjo, the son of Goguryeo's founder Jumong, founded the nation of Sipje (십제, 十濟; later became Baekje) on Wiryeseong in 18 BC, while his elder brother Biryu established himself in Michuhol (미추홀, 彌鄒忽) further to the west. The location of Michuhol is usually believed to be present-day Incheon.After some time, Biryu recognized that Michuhol's land was too barren and saline to sustain his people, so he moved to Wiryeseong with his people (Shortly after, the name of the state is changed from Sipje to Baekje). Later, Onjo moved further south because of Malgal to the north and Lelang to the east. The former Wiryeseong is called Habuk (north of the river) Wiryeseong and the latter is called Hanam (south of the river) Wiryeseong. The earthen walls of Pungnap Toseong and Mongchon Toseong in Songpa-gu, Seoul are believed by many to be the remains of Hanam Wiryeseong.During the Hanseong period, Baekje grew up against Southern Mahan and Northern Chinese Commanderies including Daifang, which attempted to violate their border. In the process, Baekje modified the political systems, and expended its territory to Mahan and Hwanghae region, and it became as a regional power. Wiryeseong served as Baekje’s capital until 475, when Goguryeo's King Jangsu attacked Baekje and captured Wiryeseong, as well as the whole Han River area, and killing Baekje's King Gaero. Baekje's next king Munju moved south and set the new capital at Ungjin (modern day Gongju city).

It has a circumference of 3.5 km. It is located in modern-day Pungnap-dong, Songpa-gu, Seoul. 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.Only 2.7 km of its walls remain. Including the west wall, which had been destroyed by flooding, its circumference reaches about 3.5 km and its area nearly 859,508 m2. After constructing this central part, the inner wall, mainly composed of sandy soil, grit, clayish soil and muddy soil, was set up by heaping earth at a slant. On the top of the last earthen layer of the inner wall, pebbles were laid in three layers and trimmed stones were piled up inside 1.5 m high with mud prepared from natural soil, and by piling up the central part in trapezoid shape whose lower part is 7m wide and 5m high.
