Siena, A Step back to Medieval Tuscany. Siena is likely Italy's loveliest medieval city, and a trip worth making even if you are in Tuscany for just a few days. Siena's heart is its central piazza known as Il Campo, known worldwide for the famous Palio run here, a horse race run around the piazza two times every summer. Movie audiences worldwide can see Siena and the Palio in the James Bond movie, Quantum of Solace.
