The cross of Santiago probably refers to the multiple conquests of the town by the Order of Santiago – once in 1186 and again in 1212. The Order was later granted the area around the town in 1243, before it was later given to Pedro Díaz de Monsalve in 1387. The reeds (or carrizos in Spanish) are drawn from the name of the town.
