A superb single-artist museum dedicated to Jean Tinguely, the Swiss sculptor whose kinetic machines clatter, whirr, and occasionally fall apart on purpose. The building was designed by Mario Botta and sits on the Rhine bank near the pharmaceutical company Roche. It houses a large permanent collection of Tinguely's work, most of which you can press a button to start moving.
Tinguely's machines are funny, unsettling, and weirdly beautiful — they comment on industrial capitalism by embodying it in absurd mechanical form. Even visitors who claim not to like modern art tend to spend longer here than they expected. Children are particularly captivated. Reachable from the city centre by tram 2 or a pleasant walk along the river.
