Palio di Siena

"Piazza del Campo" is still used today for the well known Palio horse race which is one of the most famous popular Italian manifestations. It takes place every year on July 2 and August 16. The Palio is run to celebrate the miraculous apparition of the Virgin Mary near the old houses that belonged to Provenzano Salvani. The holy apparition was therefore called "Madonna di Provenzano" in whose honour the very first Palio was run on August 16, 1656. The Palio was run for the first time in 1701 in honour of the "Madonna dell'Assunta" the patroness and Advocate of Siena through all the tragic events since she protected the Sienese militia at the famous battle of Monteaperti against the Florentines.

The Palio is a historical secular tradition strictly connected with the origin of the Contradas of Siena (districts into which the town is divided). The Contradas are spectacular agonistic institutions each having their own government, oratory, coat of arms, appellations, sometimes titles of nobility, emblems and colours, official representatives, festivities, patron Saints, with protectors, delimited territories and population which consist of all those people who were born or live within the topographic limits of the district, according to the proclamation issued by Violante Beatrice of Bavaria on January 7, 1730, at that time, Governess of the town.

Originally, there were about fifty-nine "Contrade"; now only seventeen remain, ten of which take part in the historical pageant and in the race at each Palio (seven by right and three drawn by lots).
Here is a list of their names, emblems and colours grouped into "Terzi" or "Terzieri" (in olden times the town was divided into three sections called: "Terziere di Città", "Terziere di San Martino" and "Terziere di Camollia".
