Lucy Carnegie, wife of industrialist Thomas Carnegie, dreamed of creating on Cumberland Island a home where her children would be safe from the smoke and soot-filled skies over Pittsburgh. Protected by the waters of the Cumberland Sound, the estate she built encompassed nearly the entire island. It was a perfect world until the outside world intruded. Stone by stone it all came tumbling down. Wild horses now crop the grass around the burnt-out mansion. Rattlesnakes nest among the ruins.
