the Prince of Condé known as the "Grand Condé", built a new road called rue Gouvieux, which is now the rue du Connétable. The land ceded by the château on both sides of this road formed the nucleus of the new town, as guesthouses, workshops for the artisans of the château, and lodgings for servants sprang up. This embryonic town was divided between the parish of Gouvieux in the diocese of Beauvais and the parish of Saint-Léonard in the diocese of Senlis. Louis expressed a wish in his will for a parish church near the château. Henri Jules de Bourbon-Condé fulfilled his father's wish in 1692 by building the church of Notre-Dame and creating a new parish under the Bishop of Senlis, superseding all existing parishes. Chantilly was thus established as autonomous. His grandson, Louis Henri, Duke of Bourbon, can be called the founder of the city, since he drew up the first city plans. He brought planning to the town design and renamed the rue Gouvieux the Grande Rue. After he built the Great Stables in 1721, he created a development in 1727 and sold lots for housing to court officials, holders of hereditary positions at the court of the Condés. The architectural standards for this housing were drawn by Jean Aubert, architect of the Great Stables. This housing was built between 1730 and 1733. In 1723, the Hospice de la Charité was built at the end of the Grande Rue. In the second half of the 18th century the princes furthered economic activity. Lace had been produced in the town since the 17th century but now reached its apogee. Porcelain manufacture began in 1726 and was established in the rue de la Machine in 1730. Industrial buildings were built in 1780 at the end of the Grand Canal, to take advantage of the power provided by the waterfall. The beginnings of the commune During the French Revolution, Chantilly became a commune whose which boundaries matched those of the parish. The first mayor was the administrator of the estate, André-Joseph Antheaume de Surval. The other city council members were recruited from among the château officials. The Condés were among the first to flee abroad, just days after the fall of the Bastille, on 17 July 1789. The estate was sequestered on 13 June 1792 following the law on émigrés and subsequently subdivided and sold. The first section was sold
