Siena's main square is the site of the famous Palio horse races that take place in July and August.

The magnificent complex of the Cathedral of Siena, its Duomo, houses a series of some of the most important monuments of the European artistic panorama. With its more than one million visitors every year, the Cathedral without a doubt represents the fulcrum of the entire complex, while other significant elements include the Crypt, the Baptistery and the Museo dell'Opera, all part of the impressive mass formed by the "Duomo Vecchio" (Old Cathedral), and the "Duomo Nuovo" (New Cathedral). Visitors will travel along a memorable itinerary to the discovery of self and the truth of faith through culture and art, the result of more than a millennium of Western history.

The tower, more than 290 feet high, was constructed in 1325 by Minuccio and Francesco di Rinaldo, and has the Chapel of the Piazza at its base..
