Château de Glénay, with its origins in the 12th century, began as a fortified house overseeing the Thouaret River. Over time, it transformed into a castle, witnessing various modifications and restorations, particularly after the Hundred Years' War and the Wars of Religion. Occupied by notable families, including the Vignerot de Pontcourlays, who later became Dukes of Richelieu, the castle saw visits from historical figures like Cardinal de Richelieu and Henri de La Trémoille.
Post the 17th century, ownership changed hands, leading to periods of neglect and repurposing. After the French Revolution, the castle became an agricultural estate, and the once-grand residence succumbed to nature. However, it gained historical recognition and protection in the 20th century, ensuring its preservation.
Currently a private estate, the Château de Glénay is undergoing a meticulous restoration project since 2021, focusing on restoring its original features. The efforts aim to revive the castle's historical charm, showcasing its architectural and cultural significance.
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.
