For an insightful and vivid account of the entire war, with special focus on the Battle of Normandy, the best place to head is Le Mémorial, one of Europe’s premier WWII museums. It’s a hugely impressive affair, using film, animation and audio testimony, as well as a range of original artefacts, to graphically evoke the realities of war, the trials of occupation and the joy of liberation. It is situated 3km northwest of the city centre, reachable by bus 2 from place Courtonne.
By car, follow the signs marked ‘Le Mémorial’.
All signs are in French, English and German. Audioguides (€4) are available in six languages, with different English versions for Yanks and Brits. Note that tickets are valid for 24 hours. Child care is available. There are several restaurants here. See the website for details about tours of the D-Day sites.
