A half-century of German art is on display at the Museum Küppersmühle in a mill storage building converted by Swiss Pritzker Prize–winning architects Herzog & de Meuron. From Baselitz to Kiefer to Richter, all the big names are showcased beneath the lofty ceilings, as are up to six international art exhibits annually. From the train station, take bus 934 to Hansegracht.
