After negotiating for a long time, the Château de Saint-Cloud was bought in 1785 by Louis XVI. He bought it for Marie Antoinette. She thought that the air of Saint-Cloud would be good for her children. Louis Philippe, Duke of Orléans, who had not visited the château since his morganatic marriage to his mistress Madame de Montesson, sold it for 6,000,000 livres. Marie Antoinette started changing Saint-Cloud in 1787-1788. She used her preferred architect Richard Mique. He had also decorated parts of the Palace of Versailles for the queen.
