The House Archive of the Stiftung Stadtmuseum Berlin represents the history of the SSB, its predecessor institutions as well as all former and present collections and dependencies with its file holdings, archival collections and bequests across all collections. It sees itself as a place of research and at the same time as the “historical memory” of the foundation.

The Stadtmuseum Berlin loans items from its collection of around 4.5 million objects on the history and culture of Berlin to museums in Germany and abroad.
