I googled it once I saw your post. Looks interesting.
Wife’s cousins are in France, up by the border with Italy and Switzerland. He was a kid in WWII. As he drove us around he would point out where the
Germans had massacred so many civilians here, so many over there. Still lots of animosity.
I was surprised at the amount of old fortifications still standing. We would see them on the sides of mountains or along the highways. I always wanted to get out and explore but to him it was just old stuff. He had quite a few rifles that he had picked up after the war. He had “several cubic meters” of ammo that he had picked up, as well. Saw a few old Jeep’s and trucks in back yards.
If you haven’t been to the British Imperial War Museum it’s pretty amazing. You need at least two days to see it, though.
Hopefully someone jumps in here that has been to the museum you were asking about.
