KunstHaus (Art House Vienna) / Museum Hundertwasser, Vienna

If you ever get tired of Baroque overload while in Vienna, check out Art House Vienna—where straight lines go to die and nature moves in. Opened in 1991 in what used to be a humble furniture factory, this fever dream of a museum is one of Friedensreich Hundertwasser’s wildest creations. Think of it as Vienna’s answer to Gaudí, if Gaudí had a thing for uneven floors, tree-filled façades, and ecological anarchy.

Inside, you’ll find the largest collection of Hundertwasser’s works—paintings, prints, tapestries, and architectural models—all swirling with colour and rebellion. It’s also Vienna’s very first "green museum," a place where rooftops are grassy, trees live indoors, and environmental ideals are quite literally built into the walls.

And what’s more, Art House Vienna also moonlights as a hotspot for top-tier photography exhibitions, especially in the realm of street photography. And yes, there are audio guides available—for a small fee, of course, because even rebels have to pay their bills...

As for the building itself, it’s like stepping into a daydream after a long nap in a geometry-free dimension. Floors undulate, windows peek out from places they're not supposed to, and vegetation sprouts where logic says it shouldn't. In short: it’s perfect.

Hot tip:
Don’t miss the café tucked away in the back—it’s got a terrace that practically begs you to sit down with a coffee and rethink your life choices. Oh, and there's a shop nearby, if you feel the urge to take a piece of madness home with you.
