Lucerne’s blockbuster cultural attraction is the Sammlung Rosengart, occupying a graceful neoclassical pile. It showcases the outstanding stash of Angela Rosengart, a Swiss art dealer and close friend of Picasso. Alongside works by the great Spanish master are paintings and sketches by Cézanne, Klee, Kandinsky, Miró, Matisse and Monet. Standouts include Joan Miró’s electric-blue Dancer II (1925) and Paul Klee’s childlike X-chen (1938).
