Which historic military sites have been the most memorable for you?

Normandy, especially Omaha, Pont du Hoc and Ste Mere Eglise. Gettysburg, especially Little Round Top and site where First Minnesota held the line (85% casualties).
We Americans have a very rich legacy, evidenced by the number of sites mentioned.
Makes me feel proud and humble at the same time.
Thanks for serving, all.

Punchbowl National Cemetery, Honolulu, Hawaii. Amazing to walk the grounds and realize that every single veteran interred there gave their life in service to their country. For those of us who served, this is a breath taking, deep down grabbing place.

Normandy, Absolutely. I did the all the AOs From Gold to Pont du Hoc to include Saint Mere Eglise, Arromanches, Bayeux and of course Pegasus Bridge, it was a wonderful and moving experience that I do not think be duplicated ever again. My next location to visit is Anzio beachhead and Monte Casino.

For me, Gettysburg before I was in and Arizona Memorial after I was in and flew my mother over to Hawaii and she was there when we saw it together.

Yorktown Battlefield for me. Last August, I was TDY at Fort Eustis and on the last day, I drove to Yorktown and did the driving tour. It was something driving through the area where George Washington had his command post and seeing the field where the British surrendered.

Visited back in 1983/84/86/91 in Bangkok, "Lucy's Tiger Den"! All you older vets will know
what I'm talking about.

In 1987 while I was working in the U.A.E. I went back to VietNam and visited and photographed our old American Embassy. Stayed 3 days and that was enough!

Concord Green and Lexington Bridge! One of my memorable visits!

Wow! What a Question, 3 Yrs in DC Living at Ft Myers, Washington, DC, Walking thru Arlington Cemetery, Frequently Stopping at the Tomb of the Unknown. Master at Arms to COMSPAWARSYSCOM Washington, DC. Retired in Kansas City frequent Visitor to Liberty Memorial, National WWI Memorial. Commander VFW Post Prairie Village, KS. They both Left an Impression.

Most "memorable" - like many of us, we could spend a long night defining which, what kind, and why "memorable."

But among several that stand out, would have to be the memorial at Bastogne, in Belgium.
I had business (after Navy) in Europe that coincided with my then young daughter's spring vacation - so I took her along. After finishing the business part of the trip, we took a few days to just wander and among the destinations I picked Bastonge. We walked the ground. We climbed. We gazed upon the terrain that had held so many and such thunder. And, I admit that as I stood in the center and read, aloud, the inscription that runs around those columns that I had to stop several times. I could not simply read it. I had to stop, gather myself, and continue.
Seeing any memorial is important. Walking it, feeling it, is more memorable. It was also important to tromp it all with my daughter. We need to teach history to our children, lest they repeat our, and our fathers' mistakes.

Oh - and we also saw the current intersection of that infamous road to Malmedy, featured in the movie, "Battle of the Bulge."
