One of the most popular sights in Venice, you may have to wait and/or fight for the perfect spot to view the Bridge of Sighs, but it's so iconic it's worth the effort. Part of the Doge's palace, the bridge leads to the prison and it was said that prisoners sighed as they viewed Venice for the last time before incarceration. The bridge is a must see when in Venice and the view from inside the palace itself is not to be missed.
