Interesting apartment/office complex, designed by the Austrian architect/painter Hundertwasser. Remember that most of it is still in use as housing or offices and respect the residents' privacy. The nearby KunstHausWien (see above) is a Hundertwasser building you can freely explore.
The Hundertwasserhaus is an apartment house in Vienna, Austria, completed in 1985, after the idea and concept of Austrian artist Friedensreich Hundertwasser.

Museum of Art Fakes
Unique museum devoted to art forgery. Houses a large collection of counterfeited paintings, many from highly-skilled, infamous forgers. Includes several pages of the infamous fake Hitler diaries which fooled numerous experts in the early 1980s.
Vienna House of the Arts
Even an avowed hater of modern art can appreciate this. This is Hundertwasser's (born Friedrich Stowasser in 1928) major contribution to the Viennese art world. In a time when artists often try to shock the public or merely impress other members of the rarefied gallery subculture, Hundertwasser's KunstHausWien would be a bastion against the dictatorship of the straight line, the ruler and T-square, a bridgehead against the grid system and the chaos of the absurd. Starting with the façade of the building, adapted from its prior life as a furniture factory, there is a Gaudi-in-Barcelona feel to the place. Windows peek out like eyes from curvy, rounded plaster and colorful paint. It is a Disneyland for grownups.
Wiener Eislauf-Verein
At the Wiener Eislaufverein in winter time one can skate on a big 6000 m² square.
Built between 1911 and 1913, the Konzerthaus is the homebase for the Vienna Symphony (Wiener Symphoniker), the Vienna Chamber Orchestra (Wiener Kammerorchester), the Wiener Singakademie and the Klangforum Wien.
The Akademietheater is the smaller of two performance halls of the Burgtheater ensemble. It was built between 1911 and 1913 by the architects Fellner und Hellmer and Ludwig Baumann.
Museum of public transport (formerly known as Straßenbahnmuseum / Streetcar Museum)
This museum in a former depot houses a comprehensive collection of vintage vehicles explaining the history of Viennese public transport. The exhibits include horse-drawn streetcars from 1868, a steam tram set from 1885, many electric streetcars from the 1910s until the recent past, and buses from 1949-1978, including the infamous "Reichsbrücken-Bus" which fell into the Danube but was recovered and repaired to run for many more years. The simulator of a U-Bahn train is considered the highlight among guests. Attached small gift shop. Major labels are in English and German, but some smaller items are labelled in German only.
