CASTLES CALATAYUD

Calatayud's fortress complex represents some of the oldest preserved Islamic military architecture in the Iberian Peninsula, dating to the 9th century with its iconic Ayyub Castle built circa 884–885 CE. The fortress, which gave the town its name meaning 'fortress of Ayyub' in Arabic, originally consisted of vast structures with two terraced areas, drawbridges, and defensive configurations spanning approximately 100 by 50 meters. Though largely in ruins, the site retains three octagonal towers and significant wall sections constructed from rammed earth and stone. The broader fortification complex once included four additional castles, representing a significant strategic center of Islamic Spain.

Castillo de la Peña in Calatayud is now the site of a fortress church sanctuary built atop a medieval castle, combining unique Mudéjar architecture with religious significance. According to legend, a star appeared nightly above the hill in 1120, leading to the discovery of a bell and an image of the Virgin Mary beneath a grotto. The fortress-church adopted military architectural principles unique in Aragonese Mudéjar design, though it suffered severe damage during the Wars of Independence and required substantial reconstruction between 1814 and 1826, with further losses in a 1933 fire.

Castillo del Reloj is an 11th-century Muslim fortress, also known as Castillo Real, located in Calatayud as part of a five-castle fortified enclosure surrounding the upper city. The current remains date to the 14th century and feature two access doors, a rock-carved staircase, and medieval cellars. Despite its name, the castle lacks a clock tower—that structure collapsed in the early 20th century—though it retains a historic bell gifted by Pedro IV in 1366 that still rings at local festivals, serving as a Cultural Heritage Site since 2006.

Doña Martina Castle in Calatayud, Zaragoza, is an 11th-century Muslim fortress with surviving remains primarily from the 14th century, representing one of Spain's most significant preserved Islamic military complexes. The castle features an elongated pentagonal structure measuring 140 meters, flanked by natural ravines and remarkably constructed from limestone ashlar stone with an enigmatic wooden framework employing Yemeni construction techniques. Connected to four other castles by nearly four kilometers of fortified walls encircling the upper city, the ensemble formed a formidable defensive network of Islamic Aragon. According to historical sources, Calatayud itself was founded in 716 by Ayyub ben Habib al Lajmi around the Doña Martina fortress site. Now in ruins and municipally owned, the castle stands as an important testament to medieval Islamic architecture and strategic fortification design in Iberia.
