The Museum of Art (Museum Kunstpalast) displays artwork dating from the 3rd century BC to the present day.

 Works include fine art, sculptures, and drawings, in addition to more than 70,000 items of graphic art, photos, and applied art. Highlights are a collection of glass by Helmut Hentrich and rare Italian Baroque works. 

The modern collection features Caravaggio, whose work laid the foundations of modern art, and works by Dali, Warhol, and members of the Düsseldorf School of Painting and Expressionism. 

The museum also offers theatrical performances and classical concerts, and guided tours are available.
