Centre-Val de Loire · Eure-et-Loir, France
The château of Françoise d'Aubigné, Madame de Maintenon — governess turned secret wife of Louis XIV. Behind Le Nôtre's parterre, the park frames one of the great follies of the Grand Siècle: the ruined arches of the Canal de l'Eure aqueduct, Vauban's colossal unfinished scheme to send river water to Versailles.
