The top three floors of Dortmunder U are home to an art-world star thanks to the Ostwall's far-reaching collection of all major 20th- and 21st-century genres – expressionism to art informel, fluxus to op-art to concrete art. This translates into works by Macke, Nolde, Beuys and Paik, and living artists including Jochen Gerz, and Anna and Bernhard Blume.
