By his will of the June 3, 1884, Henri bequeathed his Chantilly estate to the Institute of France. This included the Château de Chantilly, with all the art he had collected there. The chateau became a museum. This generosity led the government to withdraw the decree of exile and the duke returned to France in 1889. He died in Lo Zucco, Sicily. He was buried in Dreux, in the chapel of the House of Orléans.
