Dolmen de la Madeleine is an isolated dolmen located in a private field on the outskirts of the town of Gennes. It was probably built between 5 000-2 000 BC. There are a number of these sites in the area - but this one is said to be the largest. Like many of the larger dolmens, it has subsequently been re-used, in this case to house a bread oven. Although the bread oven is no longer in use as the dolmen is now a classified national monument, you can still see the remains of the oven.
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).
