Castle of Al-Marya de María de Huerva Monument · María de Huerva, Comarca Central, Zaragoza Fortress of Muslim origin situated on a promontory away from the centre of María de Huerva, on the other side of the Huerva river. In the 10th century, Abd al-Rahman III quartered part of his troops there before attacking Zaragoza, within the city's defensive perimeter alongside other fortresses such as those of Juslibol, Alfocea and Cadrete, until Alfonso I the Battler reconquered it in 1118. It passed through various royal tenants and lords, among them Blasco de Aragón, to whom James II granted it in 1232 in exchange for Morella. An oval-shaped walled enclosure survives, about 50 metres along its major axis, dominated by a half-ruined rammed-earth tower, along with the remains of buildings, staircases carved into the rock and zigzag entrances typical of Muslim fortresses.
