 The origins of Cocullo are closely related to the Ancient Roman town of Koukoulon, situated between Cocullo village and Casale.Cocullo is known for its singular patron saint's holiday, named "Festa dei Serpari", in which the patron saint's statue (Domenico di Sora) is transported in procession covered with many snakes (mainly four-lined, aesculapian, grass and green whip snakes).The reptiles themselves are transported in procession by local "serpari", a sort of "snake breeders", and released in the surrounding woods at the end of the holiday.
