One of Seoul’s quirkier private collections makes for a surprisingly absorbing exhibition. It focuses on the artistry of locks, latches and keys of all kinds, mainly from Korea but also with international examples, including a gruesome-looking chastity belt. The Corten steel-clad building contrasts nicely with a colourful wall mural nearby.
