Looking like a tsunami made of glass and steel, Seoul City Hall was completely redeveloped in 2013. It is a modern reinterpretation of traditional Korean design; the cresting wave provides shade (like the curved eaves found on palaces and temple roofs in Korea) over the handsome old City Hall, which was built from stone in 1926.
Seoul Plaza fronting City Hall is the scene for events and free performances most nights during the summer as well as an outdoor ice-skating rink for a couple of months each winter.
