Château Villette, 17th century château in Condécourt, France

Château Villette is a 17th-century castle set on a wooded estate with two lakes and cascading fountains. The building features slate-roofed pavilions in Mansard style, an 18th-century chapel, and an orangery for plants.

Architect François Mansart designed the castle between 1663 and 1669 for Count d'Aufflay. After Mansart's death, his nephew Jules Hardouin-Mansart added further sections to the structure.

The name Villette refers to the old fortified house on the site, not to a family; the seigneurie was sold in 1609 to Jean Dyel, whose son, Count d'Auffay, built the present château. In the 18th century the estate passed to the Grouchy family: Sophie de Grouchy married the philosopher Nicolas de Condorcet here, and Condorcet, Cabanis and Mazzei met at the château.

The château is private and not open to the public; the only way to see the interior is to book the estate for a private event such as a wedding or a photo shoot. The grounds lie along the route de la Maison-Blanche in Condécourt, about 40 km northwest of Paris. The building is a listed monument historique, so access is arranged with the owners rather than through a ticket office.

The château is not open to the public; the only way to see its interior is to book a private event such as a wedding or photo shoot. Its grounds and buildings have appeared in many films and series, including The Da Vinci Code (2006), where it served as Sir Leigh Teabing's home.
