Carcassonne Cathedral was built in the 13th century as a parish church, dedicated to Saint Michael. Following war damage in the 14th century it was rebuilt as a fortified church. In 1803 St. Michael's was elevated to cathedral status, replacing the earlier cathedral dedicated to Saints Nazarius and Celsus, now the Basilica of St. Nazaire and St. Celse.
The cathedral plan is characterised by its relative simplicity. It forms a single nave with a 20 metre high vault, lined with several lateral chapels. The chior screen has retained its 14th century stained glass. The sober façade has a single decorative feature in the form of a large rosette 8 meters in diameter, and the adjoining bell tower is relatively massive.
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.
