A typical design by Friederich Hundertwasser. Those interested in the artist can take a hike through the Kamptal valley toward Roiten, where he designed the facade of the village museum. On the way through the Kamptal valley, you pass the "Hahnsäge" (Hahn Sawmill), which Hundertwasser bought in 1966 and lived and worked there for several years.
At the beginning of the nineties, the municipality of Zwettl wanted to make the main square more attractive - Friedrich Hundertwasser was commissioned to plan it and it was completed in 1994.
