The Galerie des 20. Jahrhunderts was a joint research project held by the Stiftung Preussischer Kulturbesitz and the State of Berlin. The project systematically studied around 500 works of art (paintings, sculptures, works on paper) that were created up until 1945, owned by the state of Berlin, and kept as permanent loans in the Nationalgalerie and Kupferstichkabinett.
The results of this successfully completed project are presented in a book and in an online databbase. While the published book focuses on the historical context of this forgotten chapter in the history of Berlin’s museums, the website presents the provenances of the works studied.
