Enjoy a 2-hour tour in Siena and soak up the atmosphere of the medieval age in this UNESCO World Heritage city. Walk along the former pilgrimage road called "Via Francigena," explore the magnificent striped Cathedral, and learn about the 17 "contrade," the districts into which Siena is divided, each with its own territory, symbol, museum, and church. Admire the shell-shaped "Piazza del Campo," one of the most beautiful squares in the world, where the Palio horse race takes place every July and August.
