Erinnerungs- und Gedenkstätte Wewelsburg 1933-1945, Historical memorial and museum in Büren, Germany.

The Erinnerungs- und Gedenkstätte Wewelsburg 1933–1945 is a museum housed in a former SS guard building near the main entrance of Wewelsburg Castle in Büren. Its permanent exhibition "Ideologie und Terror der SS" (2010) fills several rooms: one covers the SS as an organisation with biographies of members and Nazi propaganda material, another the Niederhagen concentration camp with a model, prisoner clothing, and video and audio recordings of witness testimony. The memorial also includes the two lower floors of the castle's North Tower, containing the so-called crypt and a room for SS-Obergruppenführer, accessible only to a limited extent.

The castle began serving the SS as a training facility from 1933 and hosted a concentration camp called Niederhagen on its grounds. After 1945, parts of the facility were destroyed before being reconstructed as a memorial site.

The exhibitions show how SS ideology shaped daily life and what forms of resistance emerged during this period. Visitors can see personal objects, letters, and photographs that document the lives of those persecuted and those who resisted.

The museum is housed in a former SS guard building near the main entrance of Wewelsburg Castle. Entry is free. The two lower floors of the North Tower, containing the so-called crypt and an SS-Obergruppenführer room, have only limited access.
