A medialuna (literally half moon) is crescent-shaped corral used for rodeos, the official sport in Chile. They are generally 64–66 metres in diameter. Chilean rodeos are not quite the same sport famous in the American West; they involve two riders on horseback trying to herd a calf around a circular arena, attempting to pin him against several large cushions.
