Rooms and capacities
The Salle Mauvoisin is a former cart barn with an exposed timber frame, restored by an architect and designer. It mixes old and new materials, with a staircase, custom furniture and direct and indirect lighting. It opens both onto the courtyard and onto an outdoor pergola built on a structure from the Eiffel workshops. It takes 195 guests and has a professional catering area. La Grange, a second barn, can be decorated for ceremonies, musical receptions or private events. The inner courtyard covers 5,600 m², with the 18th-century dovecote at its center.
Accommodation
The Maison Mauvoisin, in the main wing, covers 450 m² and sleeps 14, plus one extra bed. Its six bedrooms carry the names of old wheat varieties: Khorasan, Pétanielle, Touzelle, Manitoba, Carlotta and Amidonnier. They sit on either side of a 100 m² living room, the former grain loft of the farm. A games room has a bar, table football and billiards, and there is a pétanque court. Le Fruitier, a separate cottage renovated in 2021, sleeps five and has a wood-fired Nordic bath.
Catering
The estate does not cook. Clients work with caterers who use the professional catering area. Partner caterers listed include Lars Traiteur, Leroy Traiteur, Erisay Réceptions and Grand Chemin Traiteur, and the estate also lists DJs and music agencies.
History and setting
Raoul de Mauvoisin, lord of Rosny, built a castle here in the 12th century, with a farm, a prison and dungeons. Its fortified layout explains its good state of preservation. The dovecote was added in the 18th century. In 1944 the estate served as a forward base for General Patton's troops during the liberation of France. It remained a working farm until 1995 and has been restored in stages since 2008. The buildings stand around the square courtyard on a 6-hectare site, and a riding center with ten stables occupies the former farm buildings.
Getting there
The address is 2 Chemin de la Mondetterie, 78270 Lommoye. The estate is about one hour by car from Paris, under 15 minutes from Giverny and about 1 h 15 from Deauville.
