The Castle of Biar stands on a hillock overlooking the town of Biar. During the Muslim rule had already news but few of the fortress, which began to be relevant to the time of James I of Aragon, remain as border castle under the Treaty of Almizra. The building lost its role during the early modern period and, although rarely used, after was used as a cemetery.
The castle was built in stone with masonry and rammed earth, which was used for the tower of homage. The building consists of two parts. On the one hand, a semicircular enclosure with four towers at the corners thereof, and on the other, a space with four cubic structures and the tower of homage. These towers and other structures are the basic defenses of the castle, and its position high on a rocky hill, the proliferation of small openings in its walls and battlements auction.
The tower of homage is the highlight of the architectural complex. Dating from the 12th century, the tower, situated on one side, was built with mortar mixture of sand and lime and reaches a height of 19 metres. Its plan is square shaped and has three floors, acquiring such an enormous importance. On the lower floor is used the called barrel vault and the other levels, second and third, use the Almohad ribbed vault which, together with those of the neighboring Castle of Villena, are among the oldest in Spain and throughout the Maghreb, as well as the only used in a military building in the Iberian Peninsula.
References:Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
