Palio di Siena
wikipedia - Roberto Vicario
The Palio di Siena (known locally simply as Il Palio) is a horse race that is held twice each year, on July 2 and August 16 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 July 2 is named Palio di Provenzano, in honour of the Madonna of Provenzano, who has a church in Siena.
The Palio held on August 16 is named Palio dell'Assunta, in honour of the biblical Assumption of Mary.
