The Château de Careil is a fortified house constructed from the end of the 14th century and enlarged in the 15th and 16th centuries. The manor had originally a defensive function, as witnessed by the crenellated curtain wall which still exists. Under the Reformation, it served as a place of worship for the protestants established in the Guérande peninsula. For this reason, it was attacked and pillaged on 11 May 1589 by the Catholic League. In 1699, some time after the Revocation of the Edict of Nantes, the manor was siezed and sold to a Catholic family. After becoming a restaurant in 1924, the site is currently a visitors' centre. A third wing of the building no longer exists; it was destroyed in an accidental fire in the 18th century.

Le Lude is the most northerly château of the Loire Valley and one of the last important historic castles in France, still inhabited by the same family for the last 260 years. The château is testimony to four centuries of French architecture, as a stronghold transformed into an elegant house during the Renaissance and the 18th century. The monument is located in the valley of Le Loir. Its gardens have evolved throughout the centuries.
