Every year since 1357, Turkey's best wrestlers - men and boys - gather for the traditional Kirkpinar oil wrestling festival in a grassy field near the Ottoman capital city of Edirne. All wrestlers wear special thick leather trousers called "kispet," and cover themselves with olive oil to make it harder for their opponent to get sufficient grip during the fight.
