San Marco - Venice. I just came back from Venice. It's a must. The square in front of it is a lot of fun. During the day, make sure to bring with you bread or rice to feed the pigeons. At night, enjoy the three dueling Cafes; each has a mini orchestra and they all take turns playing while the audience keeps moving between them
Bridge of Sighs, Venice, Italy ~ It had to be hard for a prisoner walking across this bridge into the prison cells on the other side. Knowing they'd never escape those dismal conditions, the bridge was aptly named "The Bridge of Sighs".
