Weddings and receptions
More than 2,500 weddings have been held at Corny since 1987. Ceremonies take place in the park, under the large trees or under a Berber tent, or in the Petite Grange. The Grange Dîmière seats up to 450 guests in summer or winter and keeps room for a dance floor. Its working fireplace, wooden floor and heating with two backup boilers make it usable in the cold season, with Christmas decorations in December. The Petit Manoir, with six bedrooms, a secured pool and a sauna, serves as the base for preparations, and its garden suits a cocktail. Friday dinner weddings with a Saturday brunch are offered as an alternative to busy Saturdays.

History and setting
Philip IV gave the Corny estate to the abbesses of Poissy when the abbey was founded in March 1310. After the Black Death of 1348, John II granted them the right to fell timber in the Lyons forest, and they built the tithe barn to store the tithe. Its oak frame, cut in that forest, is original. The flint walls probably reuse stone from a Gallo-Roman fort found beneath the floor. The estate was a farm for most of the 20th century, began hosting receptions in 1987 and joined the Caupona group in 2023.
Getting there
The estate is at 1 chemin de la Vieille Côte, Frenelles-en-Vexin, reached by the A13 or the Cergy to Rouen road. Les Andelys is 10 minutes away and Lyons-la-Forêt 20 minutes.
