A broad wooden hall in a naval city
Sebyeonggwan Hall in Tongyeong, Gyeongsangnam-do, was used within the headquarters of the Joseon-era navy that coordinated forces across three southern provinces. The structure is designated a Korean National Treasure. The headquarters played a central role in maritime administration and defence.
Look at the roof and the open floor
The large single-storey timber hall has nine bays across its front and five along its sides. Its broad roofline, repeating columns and wooden floor are best appreciated by walking around the building rather than looking at just one front-on photograph. The Korean name Sebyeong literally evokes washing weapons clean, a phrase visitors can read as a hope for peace after war.
More than one building
The surrounding site in Tongyeong's Munhwa-dong preserves the history of the naval headquarters, including spaces reconstructed or restored after many earlier buildings were lost. Noticing what survives and what has been rebuilt helps explain how a maritime military centre became part of the present cultural city.
