Palio di Siena in Siena
Twice each summer, on July 2 and August 16, ten of Siena's seventeen historic contrade race bareback jockeys three times around Piazza del Campo in a contest lasting about ninety seconds. Tracing to the first round-the-square race in 1633, the Palio is surrounded by days of trial runs, a medieval costume parade, and church blessings for horse and rider.
Ten of Siena's seventeen contrade send jockeys riding bareback around Piazza del Campo for three laps in a race that lasts roughly ninety seconds, the culmination of a rivalry that occupies the city for the rest of the year.
