Chulilla Castle sits on a hill overlooking the town and is the historic core of Chulilla. Its remains reflect the town's historical moments and give it a unique character.
The oldest part of castle hill is a cistern from Roman Age. During the Muslim period, the 'hisn' was established on the hilltop, consisting of a tower with a base cistern, masonry walls, and rammed earth constructions. It controlled the valley's communication routes and served as a refuge for nearby villagers. Along with Alpuente, it was the most significant castle in the region.
After the Christians conquered Chulilla and it became part of the Crown of Aragon, significant reforms occurred in the 14th-16th centuries. During this time, the watchtower was built to control the southwest territory. The castle was used as a noble residence and later as a prison for clergy.
Carlist Wars In the 19th century, during the Carlist Wars, the castle played a vital role for the Carlist cause, serving as a fortification for the pretender's troops on three occasions. The governmental army's siege ultimately led to the castle's ruin.
The castle features an outer wall, a barbican tower, a circular bastion, a vaulted room, corner towers, and the main enclosure with a tower and remains of the residence and auxiliary buildings. It also had a chapel dedicated to Saint Michael and four cisterns. Various engravings similar to those in Denia Castle can be seen throughout the site.
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).
