It's beautiful and well-maintained. The driveway to the west rear gate reminds me of the book "The Great Maulne."

Very nice and shaded circuit. Viewpoint around the castle. Very little road. We take advantage of the Normandy countryside, these cows and some inhabitants of the fields (rabbits, buzzards). A good moment of peace.
