Siena gathers around Piazza del Campo. At the meeting of three hills, the square occupies a valley where the communal government joined two market areas at the end of the 12th century. Its shell-shaped slope still draws the eye to Palazzo Pubblico: nine paving wedges, set in red brick and pale stone, are traditionally read as an allusion to the Governo dei Nove. The surrounding façades were shaped by civic rules, including a 1297 ordinance that regulated how houses opened onto the Campo.
Palazzo Pubblico, built in stages from 1297, gives the square its civic anchor. Beside it rises the Torre del Mangia; at its foot is the Cappella del Campo, an open loggia begun in 1352 as a vow after the plague of 1348. At the upper edge, Fonte Gaia marks the other end of the view. Jacopo della Quercia's original fountain was made in 1419; the fountain in the square today is Tito Sarrocchi's 19th-century copy, while the original is preserved at Santa Maria della Scala.
The Campo has long been Siena's setting for markets, games and public ceremonies. The Palio now gives that civic life its most concentrated expression: on 2 July and 16 August, the square is prepared for the race, and the historic procession brings the contrade into the Campo before the horses. The tradition took its present regular form in the 17th century. Read our Palio di Siena guide for the ritual and event-day context.
On a quieter day, pause on the sloping paving and follow the lines toward Palazzo Pubblico, then walk to the fountain at the upper end. Allow about 30 to 45 minutes for the square itself; the civic museum and tower are separate visits, with their own tickets and access conditions.
