Within 40 years, the entrepreneurial couple Siegfried and Jutta Weishaupt built up a priceless collection of modern and contemporary art. The collection is housed in the newly built privately owned museum, which has been open to the public since November 2007.
It offers 1280 sqm of exhibition space for thematic exhibitions alternating at regular intervals. Either different artists from the collection are combined or the focus is put on only one artist represented in the collection. The collection includes incunabula of Abstract Expressionism, such as Mark Rothko, and the wide-ranging oeuvre of American pop artists such as Warhol and Lichtenstein. It is also home to works of Concrete Art by artists from Europe, such as Josef Albers or Max Bill.
