This elegant museum, located 15 minutes outside of Basel in the suburb of Riehen, was designed by Italian architect Renzo Piano. It houses a world-class collection, assembled over half a century by Basel's pre-eminent art dealer Ernst Beyeler (see Art Basel in the Other Events section). The names of its collection read like a who's-who of the art world since the late 19th century. It is notable, among other things, for a permanent collection of works by colour-field painter Mark Rothko and a vast nymphéas (water lily) painting by impressionist master Claude Monet. The Fondation usually also displays excellent temporary exhibitions. No photography indoors, photos allowed outdoors.
