House of Montmorency, then was home to the Condés and finally to the Duke of Aumale, fifth son of Louis-Philippe. He willed it to the Institute of France. Le château has two parts: the Petit Château and the Château Neuf. The first was built in 1560 by the architect Jean Bullant for the constable Anne de Montmorency. The interior decoration goes back to the 18th century for the larger apartments, and was carried out by Jean Aubert, Jean-Baptiste Huet, and Jean-Baptiste Oudry. The smaller apartments redone in the 19th century are on the ground floor. The Château Neuf was built by architect Honoré Daumet between 1876 and 1882 on the site of the portion of the older building destroyed at the beginning of the 19th century. It contains paint galleries, libraries and the chapel. A gallery, built by architecte Félix Duban in the 1840s, links the two buildings. The château is surrounded by a 115-hectare park which includes 25 hectares of water gardens. The parks includes large formal gardens designed by André Le Nôtre, the Anglo-Chinese garden installed between 1772 and 1774 in the center of which is the Hameau de Chantilly, the English garden installed in 1817 around the temple of Venus on the western side and, near the forest, the La Cabotière and de Sylvie parks. The entire estate was designated a historic monument by the decrees of 24 October and December 1988. Musée Condé The Condé Museum in the château has one of the oldest collections of historic art in France and its collection of paintings is only surpassed in France by the Musée du Louvre. The museum also contains a collection of 1,300 manuscripts including the daybook Très Riches Heures du Duc de Berry. As a condition of its bequest to the Institut de France by the Duke of Aumale, the collection's presentation cannot be modified nor can it be loaned out, so it is a permanent fixture of Chantilly. The Great Stables The Grandes Écuries, which contain the Living Museum of the Horse, are among the most-visited horse-racing sites in the world. They were built between 1719 and 1740 by Jean Aubert. They are 186 meters long with a central dome 38 meters high, and could accommodate 240 horses and 500 dogs for the daily rides to hunt. Dressage demonstrations or re-enactments are held daily in the quarry. Horse shows are regularly held beneath the
