This astounding private-turned-public collection, assembled by former art dealers Hildy and Ernst Beyeler, is housed in a long, low, light-filled, open-plan building, designed by Italian architect Renzo Piano. The varied exhibits juxtapose 19th- and 20th-century works by Picasso and Rothko against sculptures by Miró and Max Ernst and tribal figures from Oceania. Take tram 6 to Riehen from Barfüsserplatz or Marktplatz.
