Hisn Yakka is the name given to an old Muslim fortress and town, predecessors of the current city of Yecla. It was inhabited between the 11th and 13th centuries, as the town was abandoned after 1266 after the Mudejar revolt and the new Christian settlers settled on the opposite side of the mountain.
Hisn Yakka was built at the end of the 11th century in the Almoravid period, but it was not until the 12th century that the town or Madina appeared on the sunny side.
After the Christian conquest of the kingdom of Murcia, the Muslim population became a vassal of the King of Castile, which made the living conditions of the population more difficult, discontent that caused the Mudejar revolt. A large part of the Mudejar population had to leave the area at the end of this revolt, and it is likely that this was also the end of Yakka.
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).
