A monumentally modern building in the Kulturforum complex, the New National Gallery was designed in 1968 by famed German architect Ludwig Mies van der Rohe. The museum, an enormous expanse of glass windows and simple symmetry, contains a small but impressive collection of international 20th-century painting and sculpture, including works by de Chirico, Dalí, Miró, Mark Rothko, and Frank Stella. Of special interest are the paintings by early- to mid-20th-century German artists Max Beckmann, Max Ernst, and Otto Dix, and two bitter and brilliant oils by George Grosz that capture the decadent despair of the Weimar years in the 1920s. The gallery also is used for special traveling exhibitions.
