Montemolín was inhabited long before our era and received the influence of Lusitanians, Beturians, Celts and the Turduli. During the Arab domination, it was also an important enclave strategically located on the border between Andalusia and Extremadura, with a powerful fortress for defense.
Although there is no record of the beginning of the fortress's construction, it may have been erected around the 12th century. The earliest known information about the fortress dates back to the year 1246 when the castle was reconquered and handed over to the Military Order of Santiago.
The walls of the fortified enclosure cover a significant length, surrounding the hill's summit that dominates the town and offers a clear view over long distances. These walls are made of rammed earth with attached prismatic towers that punctuate the perimeter. The shape is similar to a rectangle about 130 meters long and 50 meters wide, adapted to the natural defensive terrain. The foundations are sometimes made of masonry. In the southeastern flank, the remains of a barbican to protect the main gate are preserved, along with two attached towers, which were typical features of Arab fortresses. The entrance arch, made of brick and over three meters thick, is framed between two octagonal towers, projecting outward and chamfered or octagonal in profile, following a design tradition borrowed from Roman and Byzantine constructions. From the main enclosure, only remnants of seven solid corner towers remain, two of which are covered, and the other five are freestanding. There are two major towers: the Miramontes Tower and the Homage Tower.
During the possession of the castle by the Order of Santiago, very few maintenance and restoration works were carried out.
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).
