Dates back in the 13th Century, Siena's Palio is the most important event in Tuscany. Twice a  year, on 2nd July and on 16th August, it takes place in the famous "Piazza del  Campo". The competitors, le "Contrade",  are 17 in Siena,  but only 10 can  participate at the race.  A wonderful parade precedes the race, with flag holders in  medieval costumes. The jockeys dressed with the colours of the quarter, wear a metal  helmet and "ride" without saddle. Tension is very high in the square, it's a magical moment. After the start the horses are launched in a furious gallop, which can be violent and dangerous. The horse race is very fast: one minute and half for 3 laps around the square.  After the race the winning quarter celebrates the victory, everybody can participate in the rejoicing.
