One popular theory is that disgruntled townspeople attacked city councilmen with tomatoes during a town celebration. Whatever happened to begin the tradition, it was enjoyed so much that it was repeated the next year, and the year after that, and so on. The holiday was banned during the Spanish State period under Francisco Franco for having no religious significance, but returned in the 1970s after his demise.
The festival is in honor of the town's patron saints, Luis Bertran and the Mare de Deu dels Desemparats (Mother of God of the Defenseless), a title of the Virgin Mary.
What Happens at La Tomatina
At around 11am many trucks haul the bounty of tomatoes into the centre of the town, Plaza del Pueblo. The tomatoes come from Extremadura, where they are less expensive. Technically the festival does not begin until one brave soul has climbed to the top of a two-story high, greased-up wooden pole and reached the coveted ham at the top.
