Friday’s secretive ceremony at the secluded and historic San Giorgio Maggiore island was the main event of the weekend — and Sanchez’s gown, revealed just after, was a year and a half in the making.

Bezos and Sanchez welcomed guests Thursday night in Venice, with an event in the cloisters of the Madonna dell'Orto. The A-list guest roster is expected to include more than 200 people, whether from politics, entertainment, technology, and finance.

Amazon and Blue Origin founder Jeff Bezos and his fiancée Lauren Sánchez, a journalist, author and helicopter pilot, are getting ready to tie the knot in Venice, Italy. The couple and some of these celebrity guests were photographed on Friday, leaving luxury hotels in Venice for their black-tie wedding ceremony.
