From the museum website:

The Po River WWII Museum (Museo della Seconda Guerra Mondiale del Fiume Po) is a center devoted to the memory of the war events that took place in the areas along the great river Po during the Second World War. The museum collection includes moving images, photographs, documents, and historical objects from the period between the Allies’ first aerial sorties in 1944 over the area and the victorious crossing of the Po river in April 1945. The geographical position of Felonica (Mantova) is crucial, in this context, in order to understand the unfolding of those events: because its position was central to the crossing paths of the retreating German troops and because it represented the Army boundary of the 5th US Army and the 8th British Army.

The Museum is part of The North Apennines – Po Valley Park (NAPV) which is a WWII themed park created in 2012 to preserve the memory of an often forgotten phase of that conflict: the Italian campaign after the liberation of Rome. 

The museum is also  part of the Italian War Route, a collaboration of museums and research centers remembering World War II in Italy.
