Siena is a city in Tuscany, Italy. I have not been there (yet), but I'd like to go there some time. Every year they have a race called Il Palio (http://www.ilpalio.org). From the top of
Torre Mangia you can see the whole town.
Going to Siena
You can go by plane to Rome, Pisa, or Florence. From Rome it takes about three hours by train, changing trains at Chiusi. From Pisa it takes about two hours, and you must change trains at Empoli. From Florence the train goes directly and takes about 1,5 hours.
