Musée De L'Armée

A great collection of armor, arms and uniforms dating from medieval to WWII. Make sure to visit Napoleon’s tomb while you’re there. Before I visited, I kept noticing the large gold dome in Paris, and wondered what was there. There lies Napoleon, and his tomb is magnificent!
It’s not far from the Eiffel Tower, so we visited after stopping there first.

See army uniforms, badges and medals from numerous French wars, and a large section on WWI & WWII of course. As I visited the concentration camp in Dachau last summer, it was interesting to see it mentioned here again, the exibition had some pieces from several concentration camps, including Dachau.
