CHANTILLY, a town of northern France, in the department of Oise, 25 m. N. of Paris on the Northern railway to St. Quentin. Pop. (1931) 4,848. It is situated to the north of the forest of Chantilly and is one of the favourite Parisian resorts. Its name was long associated with the manufacture, now decayed, of lace and blonde ; it is still more celebrated for its chateau and its park (laid out originally in the 17th century), and as the scene of the annual races of the French Jockey Club. The chateau con sists of the palace built from 1876 to 1885 and of an older por tion adjoining it known as the chatelet. In the reign of Charles VI. the lordship belonged to Pierre d'Orgemont, chancellor of France. In 1484 it passed to the house of Montmorency, and in 1632 to the house of Conde. Louis II., prince de Conde, enjoyed here the society of La Bruyere, Racine, Moliere, La Fontaine, Boileau and others. The stables close to the racecourse were built from 1719 to 1735 by the duke of Bourbon. The grand chateau was destroyed about the time of the Revolution, but the chatelet still remains one of the finest specimens of Renaissance architecture in France. The chateau d'Enghien, facing the en trance to the grand chateau, was built in 177o as a guest-house. In 183o the estate passed into the hands of Henri, duc d'Aumale, fourth son of Louis Philippe. In 1852 the house of Orleans was declared incapable of possessing property in France, and Chan tilly was accordingly sold by auction, but passed back into the hands of the duc d'Aumale who built the palace, on the founda tions of the grand chateau. He installed in the chatelet a valuable library and a collection of paintings. In 1886 he gave the park and chateau with its collections to the Institute of France in trust for the nation, reserving to himself only a life interest.
