Château de Quintin was mentioned as 'castellum novum' in 1202 and it was probably a fortified manor built in the late 1100s by Alain de Penthièvre. Geoffroy I Boterel built the first actual castle in the middle 1200s. it consisted of a moat, four gates, curtain walls and towers. The castle was badly damaged in the Wars of Religion (1590s).
The next castle was built as a living residence in 1643 and restored in 1785-1790. During the Great Revolution Château de Quintin was used as a prison. Since 1935 it has been owned by Bagneux family.
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.
