Lucheux Castle was built in 1120 by Hugh II, Count of Saint-Pol who used techniques taken back from the crusades he had been on. Situated on the border of Artois and Picardy it was one of the most important strongholds in the region. It continued to grow during the Middle Ages. Count Guy III of Saint-Pol altered the castle with four corner towers, hall and chapel in 1275. The castle was attacked by English army during Hundred Years' War several times.
In 1522 the imperial troops of Charles V besieged Lucheux castle for eight days and in 1552 Spanish army attacked it. Protestants took it into their possession in 1567 and the final siege occured in 1594-1595 by Spanish army again. They destoyed the castle and it was finally demolished by the order of cardinal Richelieu in 1640.
Today the massive gate and some walls remain.
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.
