This is a decidedly unconventional museum created by the Viennese artist Friedensreich Hundertwasser in 1991. Although it houses some of his works, as well as those of his contemporaries, the popularity of this museum stems from its unorthodox structure and decor, with trees growing out of windows and uneven floors that imitate the floor of a forest. Colorful tiles and splashing fountains surround the idyllic garden cafe. Daily 10 am-7 pm (cafe open later). Guided tours are also available Sunday and holidays at noon. 9 euros each for the permanent and temporary exhibits, or 12 euros for both. Monday half-price. Untere Weissgerberstrasse 13 (Third), Vienna. Phone 712-0495. http://www.kunsthauswien.at.
