Amazon and Blue Origin founder Jeff Bezos and Lauren Sánchez, a journalist, author and helicopter pilot, have departed Italy after they tied the knot during a multi-day wedding extravaganza. The billionaire husband and wife were photographed waving goodbye as they left a luxury hotel in Venice.

That’s right. The wedding that took place on the small, secluded island of San Giorgio Maggiore was symbolic, not legally binding. Venice didn’t receive an official license request from Sánchez and Bezos, a city spokesperson confirmed to CNN ahead of the nuptials.
