The Piazza del Campo is in the center of Siena and Siena's premier square. The Piazza del Campo is shell shaped, symbolically uniting the different levels formed by the conjunction of the three hills on which the city was founded.

Paved in red brick and marble, the site is one of Europe's greatest medieval squares and contains the Palazzo Pubblico and the Torre del Mangia. The bi-annual famous Palio is held in the square.
