12 centuries of ceramic history, 7 centuries of glass production: the Ariana Museum documents both ceramic and glass production with over 20,000 exhibits from Switzerland, Europe, the Near East and Far East. The museum is located in a park on the banks of Lake Geneva.
The Rosengart Collection is of great importance because it houses two unique groups of works by Paul Klee and Pablo Picasso. In addition, the collection exhibits works by over 20 masters of the 19th and 20th century, including Cézanne, Monet and Matisse.
The Paul Klee Center, which opened in 2005, is dedicated to the person, life and work of Paul Klee (1879–1940). It houses the worldwide largest collection of Klee's works. Paul Klee is regarded as one of the 20th century's most important artists.
Since 1951 the former grammar school at the city park houses around 600 pictures and drawings by Swiss, German and Austrian artists. We owe this to the Winterthur art patron Oskar Reinhart.
