Seoul is geographically and historically divided by the Han River, which separates the city into two distinct areas.12

  • Gangpuk (North City): Located north of the Han River, this area contains the original city center founded in 1394 as the capital of the Joseon dynasty. It is characterized by a historical layout, including the remains of the old city walls and gates, and serves as the traditional heart of the capital.12
  • Gangnam (South City): Located south of the Han River, this area remained largely undeveloped until the 1970s. Following extensive government-supported development, it has emerged as a modern, affluent second central business district, housing high-rise office buildings, apartment complexes, and significant economic activity in technology and fashion sectors.12
