On the summit of the gypsum spur called the Montes Blancos, the Muslims built the castle of Alfajarín in the 11th century, with the mission of monitoring the banks of the Ebro and protecting Zaragoza from the east. Its structure forms an irregular floor similar to the pentagon, being defended by natural cliffs except for the north and east sides, where a defensive moat was built to protect the entrance, with access by drawbridge and defended by two towers.
