We were very embarrassed to admit to our language school professors and visitors that we hadn’t visited Siena yet. Siena is a city only an hour south of Florence and one of the most visited cities in Tuscany (and in Italy), so we didn’t have a good excuse as to why. So, today was the day. There were two major sites to see: Siena’s Duomo (of course!) and the Piazza del Campo, where the Palio is held every year.
