Yeouido (Hangul: 여의도, ) is a large island (or eyot) on the Han River in Seoul, South Korea. It is Seoul's main finance and investment banking district. Its 8.4 square kilometers are home to some 30,988 people. The island is located in the Yeongdeungpo-gu district of Seoul, and largely corresponds to the precinct of Yeoui-dong. The island contains the National Assembly Building, where the National Assembly of South Korea meets, Korea Financial Investment Association, the large Yoido Full Gospel Church, the 63 Building, and the headquarters of LG, Korean Broadcasting System, and the Korea Exchange Center. Due mainly to its importance as a financial district and its central location, Yeouido is home to some of Seoul and South Korea's tallest skyscrapers, including International Finance Center Seoul, Parc1 Tower, the Federation of Korea Industries Tower, as well as the iconic 63 Building. Etymology The name of the island means "You can have it," i.e., "useless". This was because whenever the Han River flooded, only a small patch of high ground remained above water level. History Being a vacant spot convenient to the capital of Joseon, Yeouido was used as a national pasture for sheep and goats according to a 16th-century geographical record. Yeouido remained for the most part an uninhabited sandbar prior to the construction of Seoul's first airport in April 1924. The airport served both international, domestic, and military flights, and was also the site of a flight school. The airport was prone to flooding that made it unusable during the summer rainy season. Gimpo International Airport took over Yeouido's commercial flights in 1958, and Seoul Air Base took over its military functions in 1971. Starting in the late 1960s, major housing developments were erected on the island, many of which are still in place in 2020. The six-lane bridge connecting it to the mainland of Yeongdeungpo was built in 1970 as part of Han River development project led by President Park Jung-Hee, after which followed a period of rapid development. Formerly part of Goyang, Yeouido-dong was formed as a separate entity in 1971. In 1975 the new National Assembly Building opened on the western side of the island. In 1985 the 63 building was completed and was the tallest and most well-known building in the country for many years. Politics Yeouido is the center of politics in South Korea.
