since the death of the Princess Palatine in 1722. Claude Desgots redesigned the gardens of the Palais-Royal in 1729. Louis Philippe I In 1752 Louis Philippe I succeeded his father as the Duke of Orléans. The Palais-Royal was soon the scene of the notorious debaucheries of Louise Henriette de Bourbon who had married to Louis Philippe in 1743. New apartments (located in what is now the northern section of the Rue-de-Valois wing) were added for her in the early 1750s by the architect Pierre Contant d'Ivry. She died at the age of thirty-two in 1759. She was the mother of Louis Philippe II d'Orléans, later known as Philippe Égalité. A few years after the death of Louise Henriette, her husband secretly married his mistress, the witty marquise de Montesson, and the couple lived at the Château de Sainte-Assise where he died in 1785.

It was built from 1637 to 1641 to designs by Lemercier and was initially known as the Great Hall of the Palais-Cardinal. This theatre was later used by the troupe of Molière beginning in 1660, by which time it had become known as the Théâtre du Palais-Royal. After Molière's death in 1673 the theatre was taken over by Jean-Baptiste Lully, who used it for his Académie Royale de Musique (the official name of the Paris Opera at that time). The Opera's theatre was destroyed by fire in 1763, but was rebuilt to the designs of architect Pierre-Louis Moreau Desproux on a site slightly further to the east (where the rue de Valois is located today) and reopened in 1770. This second theatre continued to be used by the
