The permanent collection, one of the largest and most diverse in Switzerland, begins with the Italian Trecento (notably Duccio and Fra Angelico) then follows Swiss art from Niklaus Manuel in the 15th century through Albert Anker and Ferdinand Hodler in the 19th and on to Giovanni Giacometti and Cuno Amiet in the 20th. The Impressionists are covered from Manet through Monet; the Nabis, by Bonnard. Picasso bridges the gap between Toulouse-Lautrec and Braque; Kirchner, Kandinsky, and Klee represent German Expressionism through Blue Rider to Bauhaus. Mondrian and Meret Oppenheim round out the 20th century. Temporary exhibits often take it from there.
