Robust fortification of the eleventh century that served to reconquer the Muslim plaza of Huesca in 1096. Sancho Ramírez ordered the construction of the Castle-Abbey, to guarantee the siege of the city, beginning the construction of the church in 1093, and founding a monastery by moving from the community of clerics of Loarre. The abbey of Montearagón had great power throughout the Middle and Modern Ages, with influence over a vast radius. The walled perimeter is hexagonal, irregular, with the church attached and forming part of the wall.
From the splendor of this castle-abbey are samples in Huesca, namely the Main Altarpiece, in the Diocesan Museum, and the tomb of King Alfonso I the Battler, in the cloister of San Pedro el Viejo
