Pinacoteca Agnelli is an art gallery that displays art from a vast private collection. You'll find Renoir's Blonde Bather and Manet's La Négresse, as well as works by Matisse, Canaletto, Tiepolo, Canova, Picasso and Modigliani. The futuristic "crystal spaceship" pavilion is an attraction in itself. The Pinacoteca is perched on top of the Lingotto complex — the headquarters of the Italian auto giant Fiat, founded by Giovanni Agnelli. It was built as a car factory in the 1920s, and was the largest and most modern plant of its kind in Europe. A winding brutalist ramp took cars to the top of the building, where they could drive the 500 m long test track. The ramp and the test track are still in top-notch condition, but the building itself now serves a different function. While its exterior remained largely unaltered, the interior was revived to house an exhibition centre, a conference centre and auditorium, two hotels, offices and shops. The iconic ‘Bubble’ — a transparent meeting room on the roof — was also added.

Tucked into the bohemian Grottes district, Les Schtroumpfs — or the Smurfs buildings — are some of the quirkiest architecture in Geneva. Built in the early ’80s by three architects with a clear nod to Gaudí and comic book weirdness, the buildings look like something out of a fairytale: rounded shapes, bright colours, and almost no straight lines. Locals named them after the Smurfs because they genuinely look like something those little blue guys would live in. The complex houses around 750 families and includes a kindergarten, a dental clinic, and a few cafés, all surrounded by trees and playgrounds. It’s not a tourist hotspot, but definitely worth a quick wander if you’re nearby.

This is the most picturesque and romantic district of Strasbourg. The alleys offer a succession of old half-timbered houses and, thanks to canals, the river Ill gives visitors the feeling of strolling in Venice. Fluvial tours of 70 minutes with explanations in several languages are available.
