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.
References:The Château de Chantilly comprises two attached buildings: the Petit Château built around 1560 for Anne de Montmorency, and the Grand Château, which was destroyed during the French Revolution and rebuilt in the 1870s. Owned by the Institut de France, the château houses the Musée Condé. It is one of the finest art galleries in France and is open to the public.
The estate"s connection with the Montmorency family began in 1484. The first mansion (now replaced by the Grand Château) was built in 1528–1531 for the Constable Anne de Montmorency by Pierre Chambiges. The Petit Château was also built for him, around 1560, probably by Jean Bullant. In 1632, after the death of Henri II, it passed to the Grand Condé who inherited it through his mother, Charlotte Marguerite de Montmorency.
Several interesting pieces of history are associated with the château during the 17th century.
