[1] The island is located in the Yeongdeungpo District of Seoul, and largely corresponds to the precinct of Yeoui-dong.

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 the International Finance Center Seoul, Parc1 Tower, the Federation of Korea Industries Tower, as well as the iconic 63 Building.

As the airport was prone to flooding, it was eventually replaced by commercial and residential construction beginning in the late 1960s.

[2] The island went by a number of names in the Joseon period, including Yanghwado (양화도) and Nauiju (나의주).

[8] 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.

[9] Yeouido remained for the most part an uninhabited sandbar prior to the construction of Korea's first airport in April 1924.

Gimpo International Airport took over Yeouido's commercial flights in 1958, and Seoul Air Base took over its military functions in 1971.

Construction of the building commenced in 1969 and was completed in 1975 and sits atop the site of the former Yeouido Airport.

Despite this, the grounds are usually open to the public and connect to the Han River Park which surrounds the site on three sides.
