Ivrea is a town and comune of the province of Turin in the Piedmont region of northwestern Italy.
Battle Ivrea today is best known for its peculiar traditional carnival. The core celebration centres around the locally famous Battle of the Oranges. This involves some thousands of townspeople, divided into nine combat teams, who throw oranges at each other • with considerable violence • during the traditional carnival days: Sunday, Monday and Tuesday. The carnival takes place in February Origin
The festival's origins are somewhat unclear. A popular account has it that it commemorates the city's defiance against the city's tyrant, who is either a member of the Ranieri family or a conflation of the 12th-century Ranieri di Biandrate and the 13th-century Marquis William VII of Montferrat.
