A glass-and-steel, modernist structure designed by Karl Schwanzer was reborn in 2011 as the 21er Haus. It houses exhibitions devoted to 20th- and 21st-century art with a predominantly Austrian focus. The bright, open-plan gallery sits on the edge of the Schweizergarten and has established itself in the contemporary art scene. The approach is progressive, with an artist-in-residence scheme and a series of numbered collections that include Austrians like Erwin Wurm, Lisa Ruyter, Franz Graf, and Lisl Ponger, as well as international greats. On permanent display is a unique collection of sculptures by Viennese artist Fritz Wotruba (1907–1975). There is also a restaurant and bar downstairs, Dots twenty-one, which is the best lunch or dinner choice in a wide radius. Since there are no direct neighbors, the DJs turn it up after hours and parties go late outdoors in summer.
