Started the last Wednesday of August in 1945 when some young people spent the time in the town square to attend the Giants and Big-Heads figures parade. The young boys decided to have a place among the retinue of a parade with musician, Giants and Big-Heads figures.
The energy of these young people made that one participant fell off. The participant flew into a fit of rage, started to hit everything in his path. There was a market stall of vegetable that fell victim of the furious crowd: people started to pelt each other with tomatoes until the local forces ended that vegetable battle.
The following year, the young people picked a quarrel by their own decision and brought the tomatoes from home. Although the police broke up the early tradition in the following years, the young boys had made history without being conscious about it.
