The Netherlands museum at Overloon http://www.oorlogsmuseum.nl/en/ comprises 'The Dutch National War and Resistance Museum' where you will experience the occupation and the persecution during WWII, but also the resistance and D-Day through a series of rooms full of photographs, videos and personal accounts and effects.
It also has exhibits telling the story of the Battle at Overloon (which was the heaviest tank battle ever on Dutch soil) during the liberation of the southern Netherlands.
Also housed at Overloon is 'The Marshall Museum' which has more than 150 historical vehicles, vessels and aircraft. Anyone even slightly interested in military vehicles will find it an unforgettable experience, particularly if you hit one of the red buttons to turn on the sound effects!!
