Louis Joseph, Prince of Cond%C3%A9
Louis Joseph de Bourbon was Prince of Cond from 1740 to his death. A member of the House of Bourbon, he held the prestigious rank of Prince du Sang.
Among other estates, Louis Joseph inherited the famous Chteau de Chantilly, the main seat of the Cond line. At Chantilly, the prince conducted a number of improvements and embellishments in the years before the French Revolution. He had the Chteau dEnghien built on the grounds of the estate to house guests when the prince entertained at Chantilly. It was constructed in 1769 by the architect Jean Franois Leroy and was later renamed the Chteau dEnghien in honour of his grandson Louis Antoine, Duke of Enghien who was born at Chantilly in 1772. He also commissioned a large garden in the English style as well as an hameau, much like the contemporary Marie Antoinette had created at Versailles and the Petit Trianon.
