The Charlottenurg-Wilmersdorf Museum was founded in 1987 and is devoted to researching and showcasing the regional and everyday history of the Berlin borough of Charlottenurg-Wilmersdorf. It also explores the cultural history of Berlin in general. Since January 2012, the museum has been housed in Villa Oppenheim, a grand home built in 1881 as a summer residence for Margarete Oppenheim (née Mendelssohn) and Otto Georg Oppenheim. Since moving to Villa Oppenheim, the museum has shown the art collection compiled by the "City of Charlottenburg" starting in 1908 – a time when Charlottenburg was still independent city rather than a borough of Berlin. The collection comprises primarily works from the 19th century and the Berlin Secession. A number of special exhibitions also highlight themes drawing on the history of the borough. In addition, the museum organises an Easter and Christmas exhibition each year. In its "Villa O. from 4–18" section, children and young adults are invited to research and discover new and interesting items and activities.
