The development of Chantilly continued under Condé's successors, and the castle was modified by Mansart. The Duc de Bourbon caused the "Grandes Écuries" to be built by Jean Aubert. He established the manufacture of porcelain there (ceased in 1870), the remaining pieces of which are greatly sought after in our day.
THE OLD CASCADES OF CHANTILLY
In 1722, Louis XV. stayed at Chantilly on his way back from his coronation at Rheims. The festivities lasted four days; 60,000 bottles of wine and 55,000 lbs. of meat being consumed.
It was Prince Louis-Joseph who saw the Revolution. He had spent enormous sums in embellishing Chantilly, besides the twenty-five million francs which it cost him to build the Palais-Bourbon in Paris, the present seat of the Chamber of Deputies. He erected the Castle of Enghien, named after his grandson, the Duc d'Enghien, who was the first to inhabit it. (Early marriages were usual in these great families: at the birth of the Duc d'Enghien his father was sixteen years old and his grandfather thirty-six.) The Duc d'Enghien died in 1804, shot in the moat of Vincennes.
The English garden and the hamlet are due to Louis-Joseph.
In 1789, after the Prince of Condé had gone into exile, the Parisians came and removed the cannon from the castle (see reproduction of engraving below, in which the castle appears as altered by Mansart). Thirty guns taken from the enemy during the Seven Years' War, which were never used except for firing salutes during fêtes, were brought in triumph to the Hôtel de Ville in Paris, whence La Fayette had them sent to the arsenal.
The great cascades, the menagerie, the orangery and the theatre disappeared during the revolutionary era.
Of the great castle nothing remained but the basement, whilst the town grew and encroached on the park.
In 1814, the Prince de Condé returned to Chantilly and commenced the restoration of the domain, a work continued by his son. The latter came to a tragic end in 1830; he was found hanging from the fastening of a window in his castle of Saint-Leu, and with him died the great family of Condé.
