The building time of Château du Hallier is not known precisely. It is recorded in the 15th century in deeds of sale. The castle was sold to Charles de l'Hospital in 1537. In the 18th century, the castle was used as a quarry; the square second floor disappeared. In the 19th century, the castle became a farm. One of the towers housed a potter's kiln until the early 20th century. Today castle is privately owned. It has been listed since 1967 as a monument historique by the French Ministry of Culture.
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).
