Katie Holmes and Tom Cruise

In November 2006, Katie Holmes and Tom Cruise—and their dozens of A-list guests including Will Smith, David Beckham, and John Travolta—traveled to Bracciano, Italy to tie the knot at Odescalchi Castle, a 15th-century estate. The wedding itself was nothing less than luxurious, with Andrea Bocelli serenading dinner guests and flag bearers, dressed in traditional Renaissance fashion, greeting attendees. Despite the lavish occasion, the couple divorced in July 2012, nearly six years later.
