Geheimes Staatsarchiv Preußischer Kulturbesitz

The Archives were originally chartered in 1282, but their existence as an independent institution was later established in 1598, when Erasmus Langenhain was chosen as the first archivist. The Archives received the name"Geheimes Staatsarchi" in 1803. The Archives moved to a new building in 1924 in Berlin-Dahlem, which remains their main building today. The Secret State Archives became part of the Prussian Cultural Heritage Foundation (Stiftung Preußischer Kulturbesitz) in 1963. 

The holdings include around 35000 linear meters of archival material regarding the Brandenburg-Prussians. This includes records of the Hohenzollerns, the Prussian army, provincial authorities and political organizations. 

Research at the Archives is free for the public, and copies are possible with a charge. Online forms can be filled out for specific record orders or to reserve space in the reading rooms (Anfrageformular, Bestellformular).
