This contemporary art space, situated on the roof of an aristocratic building dating from 1939, is actually a multi-room flat with large terraces on several levels, an outdoor swimming pool and a stunning view of all the landmarks in the city centre. The gallery organises exhibitions and runs residency programmes with international artists. Hopefully you’ll catch one of the many planned art and curatorial projects, readings, screenings and performances, but check the website first, as Swimming Pool doesn’t have fixed opening hours and is only open during events.
