Châteaugiron developed around its château from the 13th century onwards, becoming more prosperous towards the end of the Middle Ages as the canvas sail industry expanded. The town’s unique historic town centre is very well-preserved and features significant remains of the medieval fortress, renovated between 1450 and 1470 by Jean de Derval. Of the six original towers, four are still standing: the 38 metre high 13th-15th century keep, built independently of the château, the 14th-15th century clock tower, a belfry during the French Ancien Regime, and the 15th century watchtower and Cardinal’s tower, whose elevated patrol paths with machicolation projections has been preserved.
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).
