The Battle of Oranges
This is one of the most unusual festivals in Italy. The festival is held in the middle of winter during the winter carnival. The entire city of Ivrea near Turin turns into a battlefield. Oranges are thrown through the streets to recreate a legendary mid evil battle when the starving townspeople were freed from the tyranny of an evil baron.
Nowadays There are nine 'teams' that represent the different neighborhoods of the city that participate in the battle. Neighborhood teams wage a citrus civil war using tons of the fruit as artillery in a multi-day battle.
