The largest of the Loire castles, built under King Francis I, became national property during the French Revolution.
It was offered by the Emperor to Marshal Berthier in 1809, after the victory of Wagram. The latter, however, barely lived there.
At the Restoration, the State bought Chambord to his widow after a national subscription.
It then offered it in October 1820 to Henri d'Artois, the grand-son of future King Charles X, only two months old.
