Named after its owner, Madame de Maintenon, the castle of Maintenon nestled in the Eure valley. It is surrounded by a French garden with an elegant mixture of plants and minerals. It is an absolute delight to stroll around the rose beds. When the evening falls, the garden becomes a true fairy tale thanks to the light shows. Besides the beautiful gardens and refined interior of the 18th and 19th century’s apartments, the outer wall of the castle houses the unique civil engineering structure of military architect Vauban. This aqueduct should have taken the water of the Eure river to Versailles to source basins and fountains. A royal whim that was never realised.
