The former Preußenmuseum at Wesel is located in the citadel of the former fortification of Wesel. The previous focus of the museum was the Prussian history of Wesel and the Rhineland from 1609 to 1947 in connection with the historical location of the fort. With its new concept as the LVR-Niederrheinmuseum Wesel, the museum's thematic programme has been extended in terms of time and limitation to the time period above no longer applies. The regional focus is now more strongly placed on the Lower Rhine region and the Dutch-German border region.
