The Hundertwasser House is perhaps the most famous building of the 20th century outside the 1st district of Vienna. It is distinguished by the unique handwriting and manner of the artist Friedensreich Hundertwasser, whose real name and surname were Friedrich Stowasser. The facade of the Hundertwasser's house in Vienna, decorated with colorful colors, attracts looks almost magically. Those who live in the Hundertwasser's house can decorate the facades around their windows in any way. More than 200 trees and shrubs, planted on the balconies and terraces of the Hundervasser house, turn the house into a green oasis in the center of the city. The Hundertwasser House can only be inspected from the outside.
