Friedensreich Hundertwasser considered the architecture of KunstHausWien “a stronghold against the false order of the straight line, a bastion against the grid system and the chaos of nonsense.” Together with the architect Peter Pelinka, he designed a five-storey museum – a fusion of old and new, preserving as many elements as possible. KunstHausWien was opened in 1991 after a construction period of two years. The artist’s credo “Art must show its true colours again. Art must address the people again (…) Art must embrace nature and her laws and man and his striving for true and lasting values”, written down as a foundation document, was placed inside the stump of a pillar.
