Owner: Ted Turner
Purchase price: $2 million
Media mogul Ted Turner, who is one of the largest private landholders in the U.S., bought St. Phillips Island, off the South Carolina coast in 1979 - a year before he launched CNN.
The 5,512 acre-island of marsh and woodlands was a perfect fit for Turner, who is known for buying land and restoring it to its natural habitat. The purchase also included a 298-acre landing area on neighboring St. Helena island, which is inhabited by a group of Gullah descendants. The area was a communal refuge for this group of African Americans, who have maintained vestiges of African speech and customs, where they could hunt, fish and gather without restrictions. A dispute over the land resulted in a lawsuit by Turner , who eventually dropped the suit and donated 68 acres of the disputed property to the group in 2002.
The St. Phillips island remains private and is under the watch of a caretaker.
