Katia Rybolovleva and Juan Sartori exchanged their vows swearing loyalty and love to each other in front of about 60 guests who were all close relatives and friends.
It was an emotional moment for all and especially for the father of the bride, Russian tycoon Dmitry Rybolovlev, who was touched while walking his daughter down the aisle.
Katia was astonishingly beautiful in her white wedding dress which was made exclusively for her and the groom did not stop smiling and talking to the guests while waiting for the bride.
The guests were transferred from Aktio to the island via helicopters and they will stay at O’MEGA cruise ship docked on the island.
Before the wedding ceremony the guests had the chance to visit the small museum displaying personal objects and photographs of Aristotle Onassis, which was built by Rybolovleva family to honor the Greek tycoon.
Weather permitted, the guests will enjoy a lunch on the beach of the island on Thursday while some brave guests might try to swim.
According to the wedding program the guests are expected to leave on Friday.
