Le Mémorial de Caen was built in order to remember and honor to a bloody past, as well as show the chance for a brighter future in their hall Des Mondes pour la paix (Some Worlds for Peace). On the outside of the building is the phrase "La douleur m'a brisée, La freternité m'a réveilée, De mon blessure a jailli un fleuve de liberté." (The pain broke me, Fraternity lifted me, From my wound flowed forth a river of freedom.)
It's hard to decribe the whole experience at the museum, but safe to say, there wasn't enough time alotted for it. The two major wings of history are devoted to World War II and the Cold War.
For the Second World War, the visit starts with the "Failure of Peace" during the years leading up to war.

This part is also known as "The March Towards War". Next comes "France in the Dark Years", followed by "Deportation and Genocide", "The Eastern War", "World War, Total War" and ties into the Cold War section with "From One War to Another".
There were letter and diarys from dead soldier, blown-up pictures of Russian resistence fighters being hung, and countless faces of the dead on both sides of the combat. If anyone ever gets the chance to visit France, this should be at the top of the list. It's not the easiest place to visit, everyone that I saw that day had a few streaks running down there cheeks where tears had been, but not every holiday needs to be light and cheerful.
