Yeouido: Seoul's Dynamic Financial and Political Heart
Rising prominently from the Han River, Yeouido serves as a vital pulse point for South Korea.

From its humble beginnings as an uninhabited sandbar to its current status as a forest of soaring skyscrapers, Yeouido represents the rapid transformation of modern Korea.

A Rich and Transformative History
The history of Yeouido is a story of reclamation and adaptation. During the Joseon period, the island was known by various names, such as Yanghwado and Nauiju. Historically, it was an uninhabited sandy floodplain used as a national pasture for grazing sheep and goats. Some etymological theories suggest the name "Yeouido" could be interpreted as "Your Island," a joke stemming from the island's tendency to flood, leaving only the mountain Yangmalsan visible above water.
In April 1924, the island saw its first major development with the construction of Yeouido Airport, the peninsula's first airport. However, the site was frequently prone to flooding during the summer rainy season. As aviation needs evolved, commercial flights moved to Gimpo International Airport in 1958, and military functions transitioned to the Seoul Air Base in 1971. This paved the way for the massive residential and commercial development projects that began in the late 1960s.

Modern Development and Urban Growth
The 1970s marked a turning decade for the island. A six-lane bridge was constructed in 1970 to connect Yeouido to the mainland of Yeongdeungpo, facilitating rapid growth. In 1975, the National Assembly Building opened on the western side of the island, cementing Yeouido's role as the seat of government. By 1985, the iconic 63 Building was completed, standing as the country's tallest landmark for many years.
The Dual Pillars: Politics and Finance
Yeouido is uniquely divided by its functions. The western portion of the island is dominated by political organizations. The National Assembly Building sits at the far west, surrounded by a significant police presence due to its national importance. Major political parties, including the Democratic Party and the People Power Party, maintain their headquarters in close proximity to the legislature.

In contrast, the eastern side of the island serves as the engine of the South Korean economy. It hosts a dense cluster of the country's largest financial institutions, such as the Korea Stock Exchange, Kookmin Bank, Hana Bank, and Shinhan Securities. This concentration of wealth and decision-making power has turned the island into a premier global financial district.

Skyline and Urban Landscape
The skyline of Yeouido is characterized by some of the tallest structures in South Korea. Recent urban planning changes in 2024 have further accelerated this vertical growth, with the metropolitan government increasing permitted floor area ratios from 1000% to 1600%, allowing for new constructions exceeding 350 meters in height.

Recreation and Public Spaces
Despite its dense urban environment, Yeouido offers significant green space for residents and visitors. The island features five parks, most notably the Yeouido Han River Park and Yeouido Park. The latter was created in 1999 through the reclamation of land that had previously been used as a large public gathering square covered in asphalt.

The island is also a seasonal destination for festivals. Every April, the streets come alive for the Cherry Blossom Festival, and in October, the Han River waterfront hosts the spectacular Seoul International Fireworks Festival.

- Subway: The intersection of Line 5 and Line 9 at Yeouido Station provides central access. Other nearby stations include Yeouinaru, Saetgang, and National Assembly stations.
- Buses: A color-coded system serves the area, including Yellow buses for circular routes within the island, Red buses for specific Yeouido routes, and Green/Blue buses for connections to the rest of Seoul.
