La Tomatina is an annual festival held in Spain where people throw thousands of tomatoes at each other.
La Tomatina is a tomato-throwing festival where participants are not only allowed, but encouraged to hurl tomatoes at one another during a full-on, two-hour-long food fight. Its purpose is purely for entertainment. The festival carries on a tradition that started in 1945 and has now become a staple of Spanish tradition in Valencia.
La Tomatina is celebrated annually on the last Wednesday of August in Buñol, a medieval town of 9,000 located about 25 miles west of Valencia.
