palace became the Paris residence of the Dukes of Orléans until 1792. The Orléans canal, built by Philippe de France, was used by the family to transport their timber from the Orléans forest to the capital where it was sold. The canal was nationalised during the revolution. Under the regent, Philippe II, d'Orléans: He quietly increased his wife's annual allowance to 400,000 livres while he was in power. He also bought many buildings around Paris, although many were sold by his grandson. It was also he who bought the Regent Diamond (also known as Le Régent), which was kept at the Louvre in Paris.
