Three Places; Three Memories

I was driving around today thinking about places I had been. Thinking about places I have not been. I remembered three places I had been which were special in a few ways. See if you know these places. No hints 🙂

Do you know?

Each place has a special memory for me but the last one is special for a few reasons and the middle one let me visit a unique place that was not lost because of war.

Got them?
