Set in the eastern part of the Vexin français, this 17th-century château overlooks the Viosne valley within a walled estate. Built in the 1630s-1640s, it retains outbuildings from the early 18th century, including a row of connected rooms where stable stalls from a former horse-breeding operation still remain. Privately owned and inhabited by the same family since 1831, it was once the home of Hélène de Nervo, Marquise de Montgeroult, a musician and composer active before the French Revolution.
