Normandy American Cemetery and Memorial

Somewhere around 9,000 soldiers are buried in this Colleville-sur-Mer war cemetery, which overlooks Omaha Beach. Most of these lost their lives during the D-Day invasion. There's also a memorial that gives a narrative of the invasion, as well as a reflecting pool and a chapel. And about 1,500 soldiers who were missing-in-action are remembered on the Walls of the Missing, in a semicircle garden to the east of the memorial.

Many Americans who visit Normandy are partial to this cemetery and memorial in particular. One TripAdvisor user, from Massachusetts, says: "The visitor center, museum, and finally the graves of the war dead leave a dizzying impact on those who come to look, learn, and remember. … I recommend a visit here above any other sites for those interested in the D-Day invasion."

You can visit this cemetery daily, from about 9 a.m. to 5 p.m. or 6 p.m., depending on the time of year.
