The Mathildenhöhe World Heritage Site has always been an international center of attraction for contemporary art. In 1908, the building was opened with a presentation of the visual arts of the time. In 1920, an exhibition on Expressionism was held, with around 1,000 works of international importance. Now, a three-day opening celebration from September 20 to 22, 2024, will give the public another glimpse of the city's art treasures.
