The Museum Barberini in Potsdam shows impressionist paintings from the extensive collection of Hasso Plattner, the museum’s founder. More than 100 masterpieces by Claude Monet, Auguste Renoir, Berthe Morisot, Alfred Sisley, Camille Pissarro, Henri-Edmond Cross, Paul Signac, and other impressionist and postimpressionist artists are on permanent display. With 34 paintings by Claude Monet, there is no venue in Europe outside of Paris where visitors can see more works by this painter. Potsdam is thus one of the most important centers of impressionist land- scape painting in the world.
