Although the Teien museum hosts regular art exhibitions – usually of decorative arts – its appeal lies principally in the building itself: it's an art-deco structure, a former princely estate built in 1933, designed by French architect Henri Rapin. A lengthy renovation (in 2014) saw the addition of a modern annexe designed by artist Sugimoto Hiroshi.
