Downtown Seoul, also known as Seoul Central Business District (CBD) or Sadaemun-An, is the traditional heart of the city. It covers parts of Jongno District (around Gwanghwamun) and Jung District (near Seoul Station), along Sejong-daero and Jong-ro. It spans about 17.9 square kilometers and had around 106,000 people in 2015. This area is Seoul’s main business hub, with a mix of government offices, banks, law firms, media companies, shops, and hotels.

History and layout
- In the Joseon era, Seoul was protected by the City Wall. The downtown inside the wall was Doseong-an, the center of government and culture, while Seongjeosimni referred to areas around the city’s edge. City planning followed Confucian ideas, placing palaces, shrines, ministries, and markets in specific spots along important streets.
- Over the centuries, the downtown area kept its role even through wars and Korean modernization. The area around Gyeongbokgung and the main roads became a core axis for government offices and commerce.
- In the early 20th century, during Japanese rule, Keijō’s downtown was divided into Jongno and Jung Districts, partly because of the Cheonggyecheon stream. The colonial government built new government buildings in front of the old palace, changing the city’s layout.

Modern era and redevelopment
- After the Korean War, Downtown Seoul recovered but faced heavy traffic and crowded streets. In the 1960s–80s, the city pushed big redevelopment projects to turn the area into a modern central business district. This included building new offices and hotels and relocating some schools to Gangnam, which freed land for business development.
- The area remained Seoul’s financial and legal center. Major banks, insurance companies, and big law firms still cluster here, along with government offices that once dominated the district. Classic media companies and the Press Center have long been part of the downtown landscape.
- In the 1990s and 2000s, Downtown Seoul started balancing modernization with heritage. UNESCO-listed Jongmyo and Changdeokgung became important cultural keepsakes. In 2005, Cheonggyecheon stream was restored, turning a former road overpass into a pleasant urban waterway that attracts visitors and helps air quality.

Boundaries and planning today
- Downtown Seoul is not a single fixed district. It has come to mean the central stretch around Gwanghwamun, Myeong-dong, Jongno, and nearby streets, but its exact border has changed over time.
- In 2000, planners used nine local neighborhoods (dongs) to estimate the population of Downtown Seoul. In 2016, planners expanded the boundary to better include areas inside the old City Wall, creating a broader “Downtown Region” that covers central districts like Jongno, Jung, and parts of Yongsan.
- The district remains Seoul’s most important business center, ahead of Gangnam and Yeouido, with a diverse mix of industries. It also hosts many embassies and government facilities, reinforcing its political and economic prominence.

Today and daily life
- Downtown Seoul is a busy mix of offices, government buildings, big-law offices, and media outlets. It’s home to the famous shopping streets of Myeong-dong and the historic streets around Jongno.
- Traffic is heavy, despite extensive subway lines and bus networks added since the 1970s. Some of Seoul’s most congested roads run through this area, especially around Ujeongguk-ro and Jong-ro.
- The area remains a symbol of Seoul’s history, politics, and economy, continuing to evolve with new development while preserving its cultural landmarks and historic streets.
