Despite continual renovation in the capital of the New South, Atlanta boasts many buildings dating back to the Civil War. On a spirited tour of central Georgia, we visit five such venues, including the Kennesaw House and an 1848 house in Marietta, which served as hospitals in the Civil War. The first owners of former plantation houses Lockerly Hall and Barnsley Gardens drop by for visits. And at Andersonville, where 29,000 Union soldiers died in horrifying conditions, many ghosts roam the grounds.
