@Reminiscence, I suppose it depends on the role an area played during the Civil War that makes a difference. I've have taken an antebellum home tour featuring dozens of plantation homes that survived after the war. There wasn't much military activity in that part of Mississippi during the war, however. It stayed mostly under Confederate control.
I highly recommend taking an organized tour of antebellum homes if you find yourself in the southeastern part of the United States. Many of them have been converted into bed and breakfast facilities or museums.
