Property Description
Welcome to this exquisite Sullivan's Island home, a beautifully preserved historic two-story retreat. The home holds a unique place in history as the largest and most elaborate surviving structure of officers at Fort Moultrie. Originally serving as the Base Commandant's Quarters, its significance deepened during World War II when it became the residence of the chief of staff, George C. Marshall. Bearing witness to pivotal moments in history, the house later underwent a transformation, being sold and converted into a private residence. Built in 1901, with 5 bedrooms and 3.5 baths, this gem invites you into a world of history, sophistication and charm. French doors gracefully open onto the expansive wrap-around porches, establishing a seamless connection between indoor
