Anything but medieval, this museum is devoted to international design since 1945. The collection, supplemented by changing exhibitions, is in a slick, modern edifice that achieves the perfect synthesis between old and new. It's mostly built of traditional pink-sandstone ashlars, while the facade is a flowing, transparent composition of glass. The interior is a work of art in itself—cool stone, with a ramp that slowly spirals up to the gallery. Extraordinary things await, including a Joseph Beuys installation (Ausfegen, or Sweep-out) and Avalanche by François Morellet, a striking collection of violet, argon-gas-filled fluorescent tubes. The café-restaurant adjoining the museum contains modern art, silver-wrapped candies, and video projections.
