Vienna's Colorful Hundertwasser-HausFriedensreich Hundertwasser's design is quite the departure from the refined elegance of the city's most notable attractions. That's not to say, however, that it's not a masterpiece. This 1985 apartment block with a colorfully eclectic mix of Moorish, Spanish, and Venetian elements forms a unique living space complete with trees and shrubs on the roof.
