The Battle of Montaperti was fought on 4 September 1260 between Florence and Siena in Tuscany as part of the conflict between the Guelphs and Ghibellines. It was the bloodiest battle fought in Medieval Italy, with more than 10,000 fatalities. An act of treachery during the battle is recorded by Dante Alighieri in the Inferno section of the Divine Comedy.
Every year to commemorate the historic battle of Monteaperti a Committee organises the Torchlight in Monteaperti. The candlelight procession starts from the Acqua Borra and along the river Arbia lead to the place where was situated the ancient 11th century castle owned by the family of the Berardenghi.
