In 1815, at the start of the "Restoration", Louis XVIII traded the Hôtel de Matignon for the Élysée Palace, which belonged to Louise Marie Thérèse Bathilde d'Orléans, sister of Philippe Égalité, and the separated wife of the Duc de Bourbon. She promptly installed a community of nuns on the premises, charged with praying for the souls of victims of the French Revolution. Her niece inherited the property in 1822 and moved the community to the Rue de Picpus to rent out the Hôtel.
