Piazza del Campo is Siena’s remarkable shell-shaped main square, sloping towards the Gothic Palazzo Pubblico and the tall Torre del Mangia. Known locally as Il Campo, it is paved in warm red brick and divided by pale stone lines into nine sections, traditionally associated with the Council of Nine that governed the medieval Sienese Republic.
The square has been Siena’s civic heart since the Middle Ages. Inside the Palazzo Pubblico, the civic museum holds Ambrogio Lorenzetti’s frescoes of the Allegory of Good and Bad Government. The Campo is also the setting for the Palio di Siena, the bareback horse race held on 2 July and 16 August, when riders representing the city’s contrade race around a track laid over the square.
Visit Piazza del Campo to watch daily life unfold against its medieval backdrop, then look for Fonte Gaia at the upper end of the square; its marble reliefs are copies of Jacopo della Quercia’s originals. For views over Siena’s rooftops and the surrounding hills, climb the Torre del Mangia’s roughly 400 steps.
Come early or towards evening for softer light and fewer crowds, especially in summer, when shade is scarce. The square lies in Siena’s pedestrianised historic centre, so drivers should use a car park outside the centre and walk in. If visiting for the Palio, plan well ahead and arrive early: access to the square is controlled, and spectators stand for hours.
