IMPORTANT: Please note that, due to renovation work at the old Niels Bohr Institute on Blegdamsvej, no public historical tours are being offered until further notice. 

The Niels Bohr Archive (NBA) is an independent institution overseen by the University of Copenhagen with its own board of directors. Located in the Niels Bohr Building, it holds extensive archival material documenting the life and work of Niels Bohr, the institute that he established and the tradition that he created.

NBA produces its own research and publications, and makes its archival collections available to researchers worldwide. It has also developed an outreach function. Over the years it has established itself as a central institution for documenting the history of modern physics and its social and philosophical implications. It is currently working to expand its archival and research activities.
