Städel Museum

Frankfurt's leading art museum on the Schaumainkai (the Museumsufer riverbank). The Städel covers seven centuries of European art — Cranach, Vermeer, Rembrandt, Tischbein's Goethe in the Roman Campagna, Monet, Picasso — and is best known for its 2012 underground extension by schneider+schumacher, which doubled the contemporary-art display via a daylight-perforated subterranean hall under the museum garden.
