"Le Boy, an agricultural estate in the Early Middle Ages, became the residence of the Seigneurs du Tournel in the early 14th century. These being particularly troubled times (the Hundred Years' War), the property was fortified. A round corner tower remains from this period. This first castle, destroyed during the religious wars, was rebuilt in the 18th century and embellished with a Renaissance courtyard with two galleries accessed by spiral staircases. In the 18th century, the main facade was reworked with the addition of large windows overlooking a French formal garden.” (A. Boemare)
