It includes around 418 works by 254 European Concrete Art artists from the end of World War II onwards from almost all parts of Europe, including Hans Arp, Max Bill, Anthony Caro, Günter Fruhtrunk, Auguste Herbin, Richard Paul Lohse, François Morellet, Bridget Riley and Victor Vasarely.
[3][4] One focus of the collection is Concrete Art in Germany after 1945, including works by artists of the former GDR.
[4] Other special features within the collection are the group of works by concrete artists from Great Britain (including Barbara Hepworth and Ben Nicholson) and the section of concrete photography (with works by for example, Kilian Breier, Heinz Hajek-Halke, Heinrich Heidersberger, Gottfried Jäger, Peter Keetman, and Otto Steinert).
It is characteristic of Concrete art that these works do not depict the real world, but are based on the pictorial means of color, form, line, chiaroscuro, light and movement.
Since the museum was founded in 2002, the collection has been under the patronage of the respective Secretary General of the Council of Europe, since 2019 this is Marija Pejčinović Burić.
