Located at the local town hall, it contains historical, archaeological, ethnographic, numismatic and art collections, including an exhibition devoted to the history of Norwegian World War II prisoners of war once interned in the Oflag XXI-C POW camp in Ostrzeszów in German-occupied Poland.

Other chief collections include the works of painter Antoni Serbeński and artifacts from the Greater Poland uprising of 1918–1919.

Nowakowski had a good knowledge of the history of the town and shared Grundt's interest in the fate of the 1,150 Norwegian POWs once interned there at Stalag XXI-A.

In the cellar of the school, several Norwegian artifacts were discovered, including a dented tin plate engraved “Kaptein Vagn Enger”.

The collection of objects continues, and the museum has developed into an information and competence centre concerning Norwegian POWs in general.

After managing to smuggle a small camera into the camp, the prisoner used chocolate and cigarettes from his Red Cross parcels to “buy” film from the German guards.
