La Tomatina is a festival that takes place in the city of Buñol in Valencia, in the east of Spain, 30 kilometers from the Mediterranean Sea, where participants are tossing tomatoes for entertainment purposes only. Nobody is completely sure how the event started. … One of the popular theories is that dissatisfied townspeople attacked town councilors with tomatoes during the festivities in the city. From 1945, it takes place on the last Wednesday of August, during a week of festivities in Buñol. Tens of thousands of participants come from all over the world to fight in a harmless battle, in which more than one hundred tons of ripe tomatoes are scattered on the streets.
