Waldenburg castle lies at the summit of the spur that projects sharply from the crest of the mountain on the site of the original 13th century castle, commanding a superb panoramic view over a plain with a radius of almost 160 kilometers. It has been in the possession of the House of Hohenlohe without interruption since 1253. In the 16th and 17th centuries the castle was converted into a royal palace. The palace church, today the parish Church of St. Michael, was erected in 1791. The palace was gutted by fire in 1945. During reconstruction the architects were careful to preserve the outer structure, but much had to be altered inside. In the process, they rediscovered a 65-meter deep well that had been forgotten since the 15th century. Since 1971 the palace has housed the museum 'Siegel aus tausend Jahren' (Seals from a Thousand Years). Here you can enjoy examining approximately 800 seals from the collection of Friedrich Karl I, Prince zu Hohenlohe-Waldenburg (1814 – 1884), a Russian lieutenant general and founder of the academic study of seals. In the 'lower archives' can be found the small coin collection with coins and medallions of the House of Hohenlohe. Pewter figure dioramas with scenes from the life of important Hohenlohe lords with their seals and well-illustrated display panels augment the collections.
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.
