The exhibition "Swim City" will be the first to draw attention to one particular contemporary phenomenon in the urban space: river swimming as a mass movement – a 21st-century Swiss invention. For decades, cities like Basel, Bern, Zurich and Geneva have been gradually making the river accessible as a natural public resource in the built environment. This has made the river become a place of leisure, right on the doorstep and firmly anchored in everyday life. The rest of the world looks on in awe at the bathing culture in the Rhine, Aare, Limmat and Rhone. Here, cities like Paris, Berlin, London and New York see an example of how they can reclaim their river areas as a spatial resource, so as to sustainably improve the quality of people's urban lives.
