Segorbe Castle was an Arabian alcázar (palace or castle). Very little remains of the original alcázar, but the large complex was a residence of lords, dukes and kings for over a millennium.
.After the Muslim king of Valencia, Zayd Abu Zayd, converted to Christianity and declared himself an ally and vassal of King James I of Aragon, he ceded the fortress to James in 1229 and became governor general of Valencia on his behalf. The castle became a sanctuary for Zayd Abu Zayd himself when he was killed by Dynamil Zayyan until James captured the castle in 1245, and placed Abu Zayd in command of an army to assist in the retaking of Valencia.
The castle had a peak in the 14th and 15th centuries, culminating in the holding of General Courts by King Martin of Aragon, who had made the city his residence.
In 1784, urban expansion of Segorbe beyond the original medieval fortifications required further construction, and new walls were built. After the works were completed, the new walls had eight gates.
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).
