Seoul Museum of Art — Seosomun Main Building

Character

The arched stone facade facing Deoksugung-gil looks older than the museum because it is. It belonged to the 1928 Gyeongseong Courthouse, later used by Korea’s Supreme Court; when Seoul built the present art museum, that historic front was retained while the building behind it was reconstructed

Visitors pass through a judicial-era facade into galleries designed for art: broad interior openings, high ceilings and large windows draw natural light through spaces that no longer follow the plan of the courthouse. The old stone front functions almost like a surviving urban artifact attached to a newer museum

The experience

The main exhibition spaces rise through three floors above basement program rooms. The third floor contains the museum’s tallest gallery, roughly six metres high, beneath a glass pyramid dome that brings daylight into the interior. A much smaller Crystal Gallery nearby uses a tall glazed enclosure for focused installations, while the central void helps connect the upper floors visually

The branch mixes changing exhibitions with collection displays, learning spaces, talks, screenings and performances. SeMA L is designed as an open learning area rather than a conventional gallery; an art bookstore, cafe and outdoor sculpture space extend the visit beyond exhibition rooms. The museum therefore works as both a show venue and the public-facing center of a wider city museum network

The approach runs beside Deoksugung’s stone wall through a district dense with modern-era institutions and architecture. The museum’s own retained courthouse facade belongs to that same urban history, so the transition from street to gallery begins before the first artwork

History

Seoul Museum of Art was established in 1988 and later moved its main operations to Seosomun. The site had a longer judicial history: an early courthouse stood here before the Gyeongseong Courthouse was built in 1928 under Japanese colonial rule. After liberation, the building served as Korea’s Supreme Court

Reconstruction for the museum began in the late 1990s. Except for the historic front, the structure was rebuilt as a purpose-designed metropolitan art museum, and the Seosomun main branch opened on 17 May 2002. The preserved arched porch was designated a Registered Cultural Asset in 2006

Seosomun remains the historic center of a museum system that has expanded across Seoul through specialized branches, archives and residency spaces. That wider network has changed the role of the main building: it is no longer the city’s only major SeMA venue, but it remains the branch where the institution’s public identity and architectural history are most visibly concentrated

Before you go

The museum sits just behind Deoksugung and works easily with a walk through Jeong-dong. Because exhibitions rotate, the building and collection spaces provide the stable framework while the specific art on view changes; the preserved facade, upper-floor gallery volumes and outdoor sculpture areas remain part of the visit regardless of the exhibition cycle
