The Stiftung Preußischer Kulturbesitz (SPK) is one of the largest collection-based cultural and scientific institutions worldwide. The SPK includes the National Museums in Berlin (Staatlichen Museen zu Berlin), the Berlin State Library (die Staatsbibliothek zu Berlin), the Secret State Archive of Prussian Cultural Heritage (Geheime Staatsarchiv Preußischer Kulturbesitz), the Ibero-American Institute (Ibero-Amerikanisches Institut) and the State Institute for Music Research (Staatliche Institut für Musikforschung). This historically grown combination of museums, libraries, archives and research institutes under one roof is unique and allows cross-sectoral, interconnected work.
The SPK is thus a multidimensional, polylogical organization at the interfaces of science and research on the one hand and art and culture on the other. The collections and holdings are characterized by their cultural diversity, historical depth and geographical breadth; the disciplines represented in the SPK primarily include the humanities and cultural sciences, but also areas of social and natural sciences.
The SPK is a foundation under public law. Because of its outstanding importance for the whole country, the Federal Government and the Länder are jointly responsible for the SPK.
