Château de la Roche Guyon, La Roche-Guyon

The castle of La Roche-Guyon is a castle that stands on the French commune of La Roche-Guyon in the department of Val-d'Oise at the gates of Normandy on the right bank of the Seine.

The old ruined castle, dominated by its keep, at the top of the hillside received important additions in the 18th century at the foot of the hillside and a garden and vegetable garden "à la française": the vegetable garden of the castle of La Roche-Guyon.

The castle, classified as a historical monument, property of the house of La Rochefoucauld is today managed by a public establishment of cultural cooperation grouping the department of Val-d'Oise, the municipality of La Roche-Guyon, the mixed syndicate of development and management of the regional natural park of French Vexin and the State.

Enlarged and embellished on many occasions, notably during major works in the 18th century undertaken by its current owners, the La Rochefoucauld family, the former stronghold has gradually become a place of pageantry. Since 2010, the exhibition "Moving into the castle" has transformed the place into an ephemeral museum unveiling contemporary works in a gallery or a rampart, such as columns installed by Daniel Buren.
