“Many highlights from Zurich’s cultural life are lined up along the number 4 tram route like pearls on a string,” says Christian Brändle. And the Director of the Museum für Gestaltung knows what he’s talking about – after all, he regularly uses this tram line to get to his three museum buildings. They all lie along the route: the Toni-Areal In Zürich-West, the history-steeped main building near Zurich Main Station, and the Pavillon Le Corbusier on the shores of Lake Zurich.

It is not just recycling fans who will love the colorful tower near the central Hardbrücke Station, which boasts 17 stacked shipping containers rising 26 meters (85 feet) into the air.

The rusty containers were sourced especially from Hamburg and transported to Zurich by train. Not just nice to look at, the tower is accessible as well. Over four floors, it contains the world’s largest selection of “individual recycled freeway bags” from the renowned Zurich label Freitag – 1,600 bags.

Climb further and you’ll reach the roof of the recycled skyscraper that offers a commanding view of the former industrial quarter. Look out for old factories pulsing with new life, Frau Gerolds Garten – a popular urban garden with dining options – and the arches of the viaduct that now house gorgeous boutiques, restaurants and event spaces.
