Kunst Haus Wien. Museum Hundertwasser (Vienna Art House)
This magnificent building was constructed to house all the Imperial Hapsburg collections in one place, although these grew to occupy the Hofburg and Schönbrunn Palace too. The grand staircase provides passage to the galleries, which include the Antiquities, Egyptian-Oriental and Coin collections. The Kunstkammer (art chamber) houses sculpture and decorative arts. The Gemäldegalerie (picture gallery) has works by Old Masters, including Dürer, Raphael, Rembrandt, Rubens and Titian as well as the most comprehensive collection of Brueghels in the world. The twin building directly opposite holds the old fashioned but superb Museum of Natural History.
