The painting gallery lets you familiarise yourself with the romantics of the Düsseldorf school (Cornelius, Rethel, etc.), and the German impressionists and expressionists (Corinth, Kandinsky, Klee, Nolde, etc.). Don't miss the important glassware collection covering all periods and all continents, and the unmissable Art Nouveau creations. Also see the very rich prints cabinet (graphic works of the 15^th to 20^th centuries).
