The origins of the settlement are unknown, but Ambrosio de Morales has identified Cetina as Certima or Celtima, a
Celtiberian fort which was conquered by the Roman general Graco in 179 CE. The town lies on the Camino del Cid, the path taken by the medieval warrior, Rodrigo Díaz de Vivar, known as
El Cid, according to the anonymous medieval poem, "
El Cantar de Mio Cid", which follows the course of the
river Jalón. The relevant lines state that "and they entered the plain of Torancio, and halted between Ariza and Cetina; great were the spoils which they collected as they went along." Cetina was granted its own
fuero (law) by Guillén de Belles and
Ramón Berenguer IV in the late 12th century. In 1808, during the
Peninsular War, the pueblo was pillaged by 18,000 French soldiers, commanded by
Marshal Ney who occupied the area. ==Buildings of interest==
