Things to see
The Piazza del Campo is the famed shell-shaped town square that hosts the Palio horse race. It also houses the Palazzo Pubblico and the Torre del Mangia, two stunning examples of Sienese medieval architecture. The Duomo di Siena, located near Piazza del Campo, is a beautiful 12th century Romanesque-Gothic cathedral housing an impressive collection of artworks. These include the famed lion-decorated pulpit by Nicola Pisano, perfectly preserved Renaissance frescos by Domenico Ghirlandaio, and bas-reliefs by Donatello, Lorenzo Ghiberti and Jacopo della Quercia.
The lush hilly countryside that surrounds Siena is also well worth exploring. Perhaps consider stopping in one of restaurants in town to taste the delicious local cuisine and try some of the wines from the area.
