The shipping billionaire — and later husband to Jacqueline Kennedy Onassis — owned Skorpios, a private island on the Ionian Sea.
It was first bought in 1963, and upon Onassis’s passing, the island was transferred to his eldest daughter Christina, and then in turn to her daughter Athina, who is now the only surviving heir. Aristotle Onassis, his son Alexander, and his daughter Christina were all buried on the island.
Michael Schumacher
This island was given a gift to Michael Schumacher by Dubai crown prince Sheikh Mohammed bin Rashid Al Maktoum and its worth is $7 million. The only way to reach this isolated island is by boat or helicopter.
Believe it or not, but this isn't a real island; it's actually one of 300 human-made artificial islands.
Tatiana Casiraghi
Princess Caroline's daughter-in-law arrived with an extraordinary dowry when she married Pierre Casiraghi back in 2015: a set of five private islands.
The collection of islands has been owned by the Casiraghi family since the early 1700s. The Borromeo islands — which also hosted the couple's wedding — features terraced gardens, Renaissance dwellings, separate churches, a convent-fort, as well as strict privacy.
Brooke Shields
For years, Brooke enjoyed her Emerald Island while enclosed by towering trees, the privacy in the middle of Chazy Lake, which belongs to the gorgeous Adirondacks Park.
The Islet has a small, tree-lined private dam that connects to the shore, but apart from that, this 8.5 acres piece of earth is completely secluded.
Alejandro Sanz
Alejandro Sánchez Pizarro, better known as Alejandro Sanz is a Spanish musician and composer. Alejandro has won 17 Latin Grammy Awards and three Grammy Awards. He has also purchased a 700-acre island in the Bahamas for $16 million.
A hotel property already existed on the island when he purchased it, but as the new owner, he may develop it further.
