The Palio di Siena is a horse race that is held twice each year, on 2 July and 16 August, in Siena, Italy. Ten horses and riders, bareback and dressed in the appropriate colours, represent ten of the seventeen contrade, or city wards. The Palio held on 2 July is named Palio di Provenzano, in honour of the Madonna of Provenzano, a Marian devotion particular to Siena which developed around an icon from the Terzo Camollia.
