There is an excellent WW2/D-Day Museum in Caen, well worth a visit … but a lot of what’s inside, most of it actually, is audiovisual … so you’ll just have to take my word for it.
About 30 klicks or so outside, however, is La Coupole, the remains of the prime German V2 site in France … where rockets would have been assembled from components brought in from elsewhere, prepared and then rolled out to twin launch sites in the adjacent quarry.
Or it was … until about 2-3 months before it would have been completed in early 44 when the Allies bombed the crap out of it. They didn’t destroy it, actually, but it was damaged badly and, after the war, they did do a number on it for security reasons (afraid the French were going to be taken over by the Commies, I guess … reds under the beds … )
In the last decade or so the locals have excavated it and opened up the main levels under the damaged dome as museums … one on the V weapons and the Resistance in the area during WW2.
Again, a lot of the stuff inside the museum was audiovisual and the few physical artifacts were poorly lit or in cramped spaces that made it impossible to capture accurately. Couldn’t get an angle on the V2, for example, no matter what I tried.
The D-Day Beaches
The next several days I spent hitting the various D-Day Beaches (not all by any means) and on a trip up to Cherbourg.
The location of the famous tapestry … rubbish lighting make it impossible to capture on a camera. However, there are some displays in the museum upstairs that are of interest.
Not much in the way of easily accessible WW2 stuff there … but the Cite de la Mer had Le Redoubtable on display, one of the very first French nuclear ballistic missile subs.
