U.S. actor Tom Hanks (R) and his wife Rita Wilson (2nd R) watch the Palio horse race in Siena's main square July 2, 2007. Every July 2 and August 16, almost without fail since the mid-1600s, 10 riders have hurtled bareback around Siena's shell-shaped central square in a desperate bid to win the Palio, a silk banner depicting the Madonna and child.
