It had a marked defensive character since it takes a tower as a vertebral column. It is a question of a building of prismatic form, with hexagonal irregular plant.

At present it is the headquarters of the names of origin of the peach of Calanda and of the oil of the Low Aragon and the headquarters of the workshop of archaeology.
