Château de Talmont was founded by the Count of Poitou in the 10th century and the first documentary records appear between 1040 and 1046. In 1138 the castle was held by Joscelin de Lezay, who was attacked by Louis VII; despite being considered invulnerable because it could be resupplied from the sea, the castle was burnt by the king. Talmont passed on to the Mauléons by the 1140s, but in 1182 Richard I of England became the lord of Talmont; he remained in control of the castle until his death in 1199, when it was returned to the Mauléon family.
The castle was enlarged during by the King Richard I of England with round towers, curtain wall and new gate. Most of the castle was demolished in the 17th century.
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).
