Seoul City Hall’s Hidden Underground Space — A Guide to the New K-Culture Station

LIVING INDEX · SEOUL / NEW SPACE GUIDE

Between City Hall Station and Euljiro 1-ga, Seoul has opened a 335-meter underground space that had been closed for roughly four decades. Now called the K-Culture Station, it keeps much of the raw concrete tunnel structure while turning it into a permanent cultural venue.

Why the space matters

The unusual part is not only the program but the infrastructure itself. The corridor is believed to have been created when two subway stations at different levels were connected in the early 1980s. Its long tunnel form and exposed concrete make it feel more like discovered urban archaeology than a conventional gallery.

How to visit

Use City Hall or Euljiro 1-ga as your starting station and confirm the current entrance and exhibition access on Seoul’s official listing before departure. Because programs inside the space can change, do not assume every exhibition is walk-in or free without checking the specific event page.

Build a central-Seoul route

The strongest itinerary is City Hall → K-Culture Station → Euljiro rather than treating it as an isolated attraction. Deoksugung and Jeong-dong work well before the underground visit; Euljiro’s cafés and small creative spaces work afterward.

DESIGN TAKEAWAY
The K-Culture Station is a useful example of Seoul turning leftover transport infrastructure into cultural space without erasing the character that made the site unusual in the first place.
