The Château de Lassay is a 15th-century castle in Lassay-les-Châteaux. The first mention of a castrum in Lassay dates back to the 12th century. Owned by Charles de Vendôme at the beginning of the 15th century, the castle was destroyed by French troops as Charles de Vendôme supported the English during the Hundred Years War.
In 1458, the French king Charles VII allowed the son of Charles de Vendôme, Jean II, to rebuild a castle. The new castle was achieved within one year. The barbican was built in 1497-1498.
Since then, the castle has been left mainly intact and the original 15th-century architecture preserved by the different owners of the castle.
The castle is listed as a Monument historique since 1862. It is open for visiting from April to September.
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.
