In contrast to the courtly history of the castle, the bourgeois history of the place was not documented. In 1945 the town archive in Rheinsberg was burnt down. To fill this gap, the museum established a collection of town history in 1993.
Since 2004, the association "Stadtgeschichte Rheinsberg e.V.", co-founded by the museum, has continued this work. Results of local historical research:
- 2001 Documentation »Forced Labor in Rheinsberg«
- 2005 Publication »Jews in Rheinsberg«
