Skorpios Island, Greece
Providing a spectacular backdrop for the wedding of Jacqueline Kennedy to shipping magnate Aristotle Onassis in 1968, Skorpios Island helped to launch the modern notion of a private island as a must-have accessory for the super-rich [source: Private Islands]. Purchased by Aristotle Onassis in 1963, this lush 32-acre (12.9-hectare) island had an estimated value of $200 million in 2003 [source: Thompson and Goldman]. The island is now owned by Athina Onassis, the granddaughter of Aristotle.
Skorpios is located in the Ionian Sea, to the west of the Greek mainland, and features tennis courts, Jackie's own "Pink House" villa, two guest villas, a farmhouse, and several secluded coves and sparkling beaches, not to mention several beach cottages, its own power plant and a block of housing for the year-round staff [source: Webb].
