Now in its 73rd year and attended by approximately 30,000 people annually, La Tomatina basically involves participants hurling more than 100 tons of overripe Spanish tomatoes at each other until everyone is pretty much soaked through! Held in the pretty Valencian town of Buñol, on the east coast of Spain, La Tomatina is essentially a giant food fight held on the last Wednesday of August. The firing of a water canon heralds the start of the tomato throwing, and exactly one hour later a second firing signals the end of the messy mayhem. There are conflicting stories about how the festival first began: some say it happened when two boys got into a fight during a parade and began lobbing tomatoes from a vegetable stand at each other. Others believe that the tomatoes were thrown to protest about an unfavourable decision by the city council or launched at a particularly bad musician!
