Château d'Anet
Before his death in 1531, Louis encouraged the marriage of Prince Henry to the Pope's great-niece, Catherine de' Medici, thus setting up the triangle that was to continue until Henry's death, with his widow, Diane de Poitiers, becoming Henry's mistress. For Diane, King Henry II rebuilt the old Château d'Anet, which became one of the first French Renaissance châteaus, and she would be entrusted with much of the management of royal court business.
