Château d'Hazeville hosts seminars for 10 to 120 participants and weddings for 50 to 160 seated guests, with four modular rooms, exclusive use of the estate and 45 beds on site. A marquee in the park raises the capacity to 150 for a convention and to 400 for a wedding. The château is a manor in the French Vexin regional nature park, at Wy-dit-Joli-Village in the Val-d'Oise, about 40 minutes from Paris and La Défense.
Seminars and company events
Seminars are built to order, and the estate is open all year. Four modular rooms of different sizes take study days, residential seminars and team events, and the whole estate is reserved for one client. Basic audiovisual equipment is provided, with a video projector, a screen and a microphone; larger set-ups are arranged with outside technicians. Catering comes from a list of partner caterers. On-site and nearby activities include a pasta workshop at Pâtes du Vexin, wine tastings and champagne sabering, kayak and bike outings, and electric mountain bikes, with the Paris to London cycle route three minutes away.
Weddings and receptions
Weddings are the estate's main activity. Couples choose from ten partner caterers and are free to pick other suppliers; only the fireworks provider is imposed. The civil ceremony takes place at the town hall, while a secular or religious ceremony can be held in the gardens, the park or the salons. There is no curfew on music, with limits of 104 dB indoors and 80 dB outdoors. A second day can be booked for a brunch. Christenings, birthdays and garden parties are also hosted.
Rooms and capacities
The two reception salons are named after Charles Percier and Pierre Fontaine, the architects of the Empire style. The estate also mentions Egyptian rooms. Indoor rooms seat up to 160 and are heated in winter. Outside are a covered area, a 3,000 m² square courtyard and a 6,000 m² park with a swimming pool. Furniture covers 160 chairs, round tables for 8 and 10 and rectangular tables. The catering office has stainless steel tables, a sink and two fridges. Parking takes 200 cars, and coaches can drop off in front.
Accommodation
The estate has 45 beds. The 16th-century dovecote holds two round suites, Duchesse de Villars and Gabrielle d'Estrée, for six people. The 150 m² Loft sleeps 12 in six single rooms, one double and two twins, with a 1,000 m² garden. An accessible gîte sleeps nine on one level, and the former cider house sleeps 18 in capsule beds. Rooms are reserved for the event on the night of a reception and can also be booked on weekdays.
Catering
There is no in-house kitchen team. Seminars and weddings are catered by partners from the estate's list, using the on-site catering office.
History and setting
The estate describes itself as a 16th-century manor reworked in the 19th century by Pierre Fontaine, architect to Napoleon, and is listed as a historic monument. Its layout follows the Vexin pattern of a square courtyard, a seigneurial dovecote and dressed-stone outbuildings. Thibault and Marie, a young couple, run the estate.
Getting there
The château is reached by the A15 motorway. Travel times are about 40 minutes from La Défense, 45 minutes from Porte Maillot, 55 minutes from Charles de Gaulle airport and 15 minutes from the RER A station at Cergy-le-Haut, then a taxi. Shuttles from Paris and the airports can be arranged, and helicopter landings are possible on request.
