Panser- & Artillerimuseum
Oksbøl Varde in Denmark has a average size but realy nice museum with artillery pieces, tanks, uniforms and a great set of firetrucks. We share only some website related WW2 items, but they have weaponry from muliple timeframes in the museum. There is a little shop as wel, the museum will keep you busy for an hour and half to two hours.
