Photos of this year's "battle of the tomatoes", the "tomatina", held in the town of Bunol near Valencia. I'll summarize:
Over 40,000 people attended the annual event in which about 100,000 kilos of tomatoes were thrown. Not a single visitor or wall remained dry as the city was drenched in a reddish broth.
The origin of the annual spectacle is a matter of speculation: one story tells that during the famine of 1944, a political argument between two families turned into a tomato fight. Others claim that during the '50s some youths made fun of a street musician and threw vegetables at him. According to that tale, the musician was prompt to strike back.
The spectacle, which takes place on the last Wednesday in August, has become an international attraction since 1970.
