21er Haus

The modern glass-and-steel building known as the 21er Haus was in fact constructed in 1958 as the Austrian pavilion for the World Expo in Brussels. After the fair, the venue was painstakingly taken apart, transferred and rebuilt in Vienna on its current site near the Belvedere Palace. Originally called 20er Haus, the institution has been renamed to reflect the current century and today houses an excellent collection of contemporary Austrian art, a sculpture garden on the grounds and a basement-level café and theater.
