Constructed between 1406 and 1410, Amiens' massive square belfry has a mid-18th-century top reaching 52m, which was rebuilt after it was damaged in 1940 by German bombing. The tourist office runs two guided tours per month, one including a cathedral tour, plus night-time visits in July and August – check the website and reserve well ahead.
Today the belfry is part of the UNESCO as a World Heritage Site The Belfries of Belgium and France, a group of 56 historical buildings.
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.
