Museum Ritter

The Museum Ritter was founded for the wide-ranging art collection that has been amassed by Marli Hoppe-Ritter, the co-owner of the Ritter Sport company. The museum opened its doors to the public in September 2005. With three to four exhibitions per year, it presents works from the collection on the subject of the square. Furthermore, solo exhibitions are also dedicated to individual artists in the collection while special exhibitions focus on specific themes pertaining to the collection. Since the 1990s, Marli Hoppe-Ritter has assembled over 1,200 geometrical-abstract artworks from the 20th and 21st centuries, thus giving the collection a unique profile worldwide.
