Walk on the street that continues along the river until you get to the Ponte Vecchio, or old bridge, lined with shops. Built in 1345, this was the first bridge in Florence to cross the Arno River. It's also the only medieval bridge to survive the bombings of World War II.
Cross the river on the Ponte Vecchio and continue walking straight to Piazza della Signoria (slightly off to the right). This square is the heart of Florence's historic center. You'll see lots of sculptures around the square and in the loggia, including a copy of Michelangelo's David.
Next we're going to see what is probably Florence's oldest building. Exit the piazza on the north and walk up Via dei Cerchi.
