The ceremony reportedly took place at Forte di Belvedere, a 16th-century-era fortress near a river, and capped a week of wedding-related festivities in Europe.
In addition to shopping in Paris on Wednesday and enjoying a bachelorette party on Thursday night, the activities included a intimate pre-wedding brunch at fashion legend Valentino's chateau on Friday and a Friday night party at the Palace of Versailles in France.
Lana Del Rey performed at the Palace of Versailles bash, which included horse-and-carriage arrivals and hundreds of guests, according to E! News. The wedding party and guests then flew Italy on Saturday.
