The Château des Tourelles was built originally in 1196, when Philippe Auguste (Philip II of France), fighting against the king of England, Richard the Lionheart, for possession of Normandy, seized Vernon and made the town a military base. The castle consists of a square tower surounded by four round turrets, the whole edifice rising to a height of twenty metres. It is one of the few castles in France which has been practically unchanged for 800 years. The property of the commune, it has been listed since 1926 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).
