Le Corbusier designed a ramp museum in Japan which was completed after
his death.

The organization of the building is based on a spiral within a square. An upper level of galleries wraps around a central double-height court, penetrating it with balconies at several locations. A ramp within the skylit central court winds its way to the upper gallery level. In addition a pinwheel pattern of circulation along linear paths leads to the exit stairs.
