The Bridge of Sighs is one of the most photographed sights in Venice. Its ornate stonework design was created in 1603 by Antonio Contino, nephew of the architect who designed the Rialto Bridge. The structure got its name from the tale that asserts convicts who passed through the covered bridge from their interrogation to their prison cell would let out mournful sighs when catching their final glimpse of Venice through the barred windows. You can sigh over this same view while walking over the bridge during a tour of the Doge's Palace, the only way to make the crossing.
Both the palace and St. Mark's Basilica host millions of visitors each year, so it is important to book a guided tour for skip-the-line access, saving hours of time in long lines. Joining a small-group walking tour is an excellent way to see the highlights in and around St. Mark's Square, accompanied by a tour guide who can explain this fascinating city's history and architecture.
