Landstraße: Hundertwasser and the Stadtpark
The undulating tree-house apartments, the river, and the gold Strauss in the park. This is a Claude-drafted route awaiting the editor's walk.

1. Hundertwasserhaus
The reason you came: Friedensreich Hundertwasser's 1985 social housing, where no two windows match, the floors undulate so 'the foot can read the ground', and trees grow out of the walls. It's people's homes, so you admire it from the street corner — but the corner is enough. Look up; the gold onion domes are easy to miss.

2. Kalke Village
Directly opposite the house, the same architect turned an old tyre shop into a wandering little arcade of uneven floors, columns and a fountain. It's frankly a souvenir trap — but the floor that tilts under you is the cheapest way to feel what Hundertwasser was on about. Walk through; buy nothing.

3. KunstHausWien
A few streets on, Hundertwasser's museum of his own work, in a converted Thonet furniture factory he reskinned in the same wonky, colour-blocked style. Now the city's museum of photography too. Go in for the permanent Hundertwasser floor; the building is the exhibit even before you buy a ticket.

4. Wien river promenade
Drop down to the *Wienfluss*, the small canalised river that runs in a stone channel toward the centre. It's not pretty in the postcard sense, but the walk along it is quiet and direct, and it delivers you to the Otto Wagner portals at the edge of the park. Follow the water upstream.

5. Stadtpark river portals
Where the Wien river enters the *Stadtpark*, Otto Wagner built a pair of Jugendstil pavilions and balustrades in white stone and green iron — 1900s civic engineering dressed as art. Most people walk straight past them to the statues; you should stop. This is the quiet wonder of the walk.

6. Johann Strauss monument
The gilded Strauss, fiddle under his chin, inside a marble arch of swooning nudes — the most photographed statue in Vienna and worth the cliché. The *Kursalon* nearby still runs the waltz concerts the park was half-built to host. End on a bench by the pond; the U-Bahn is at the gate.
