Château de Villiers-le-Mahieu hosts residential seminars for up to 150 people, with 98 bedrooms, 14 meeting rooms and a restaurant for 206 guests indoors. It is the first house of Les Maisons de Campagne, set in a 12-hectare park in the Yvelines, 45 minutes from Paris.
Seminars and company events
During the week the château works as a business venue. The official pages give a maximum of 150 people for a seminar and describe meeting rooms equipped with a wireless presentation system, audiovisual equipment and office supplies. Some sessions can move outside to the garden or to sofa corners, which the team presents as an alternative to classic work tables.
The residential package covers a meeting room, a buffet lunch, coffee and snack breaks, an aperitif and an after-dinner, a plated dinner, a bedroom in single, double or twin use with a buffet breakfast, and self-service activities. The organizer's advisors help design each day with the group. A welcome with fresh juices opens the day, and a plenary room is part of the offer.
Weddings and receptions
The group lists private events among its offers, but the pages provided for this venue do not describe wedding packages or give capacities for them. Ask the team for details if you plan a celebration rather than a seminar. Two outbuildings are described as available for private hire among friends or family: La Grange and Le Cottage.
Rooms and capacities
The château has 98 bedrooms and 173 beds. The seminar page counts 14 meeting rooms and the group's overview page counts 12, so confirm the exact number for your dates. The maximum seminar group is 150, and the restaurant takes 206 people indoors.
Beyond the main building, La Grange has 9 bedrooms and 2 salons and can be taken privately. La Ferme has 43 bedrooms, bright dining rooms, a terrace, a glass-roofed hall and an inner courtyard. Le Cottage has 5 bedrooms, a dining room and a living room.
Accommodation
Rooms are booked in single, double or twin use, with a buffet breakfast the next morning. The accommodation is spread across the château, La Ferme, La Grange and Le Cottage, which lets a large group stay on the estate. The spa offers a fitness room, a sauna, a hammam and an indoor pool. The outdoor pool is open daily from 8 a.m. to 8 p.m. from June to September.
Catering
Meals are organized by the house. Lunch is a buffet prepared by the chef with fresh products for all diets, and wine, water and soft drinks are included in self-service. Dinner is a plated menu with starter, main course, cheese and dessert, the same for all guests and changed weekly with the season. The bar gives access to an aperitif and, after dinner, a drink and a candy bar until 2 a.m.
History and setting
The château was built in 1642 on the remains of a 13th-century fortress and keeps its moat. A gate, a double row of lime trees and a driveway across the moat lead to the building. The estate holds the Clef Verte label. Free activities on site include two tennis courts, bicycles, rowing boats, pétanque, mölkky, table tennis and a golf practice area, which gives teams something to do between sessions.
Getting there
The château is in Villiers-le-Mahieu, in the Yvelines department (78), about 45 minutes from Paris. The pages do not name a train station or give driving directions, so ask the team about transfers and parking before your date.
