The Condé museum is the duc d'Aumale's creation. Whilst in exile in England he collected paintings, furniture, books which are all on display in the Château de Chantilly. The Condé museum, one of France's most prestigious heritages and is the first museum for classical paintings after the Louvre.The Antechamber and the Salle des Gardes date from the 19th century. They were built by Honoré Daumet to link the Grand Château to the Petit Château, which up til then were separated by a moat spanned by a covered bridge. During the French Revolution the château was emptied of its collections, but the antechamber has several reminders of how Chantilly was decorated in the 18th century, such as the mineralogical cabinet by George Haupt (1741–1784). The mineralogical cabinet by Haupt was given to the Prince de Condé by Gustav III, King of Sweden.
