Château de Motteux can host seminars, study days, leadership retreats, product launches, company parties and weekend weddings. Its rooms, from 60 to 240 m², take up to 200 guests seated and 300 at a cocktail, and the whole estate is booked by one client at a time. The Renaissance château stands in a 23-hectare walled park at Marolles-sur-Seine, in southern Seine-et-Marne, about one hour from Paris.
Seminars and company events
The estate sells day, half-day and evening formats: study days, training sessions, conferences, business meals, product launches, executive committee meetings, end-of-year dinners and exhibitions. The main room measures 240 m², has daylight and can be set theatre style for a plenary, in a U or cabaret for workshops, or for a gala dinner. Smaller rooms serve as break-out spaces. Video projection, sound and technical equipment are provided.
A two-day residential seminar works on site: a study day, dinner at the château, a night in the chalets and a second session the next morning, with no transfers. Team activities in the park include a multi-activity challenge and a giant outdoor quiz, and partners organize balloon flights, a murder party, water sports and orienteering in the Fontainebleau forest nearby.
Weddings and receptions
For a wedding, the estate is reserved from Friday afternoon to Sunday noon. The Grange Henri II, a stone barn with its original frame, hosts a non-religious ceremony. The drinks reception takes place on the Terrasse des Écuries, facing the park, and the Salle Médicis hosts dinner and dancing with no closing time. The Boudoir Médicis is set aside for the bride's preparation, and the Salon Napoléon can be added for the drinks or as a children's room. Napoléon III chairs, round tables of eight and buffet tables are included. Birthdays, christenings, bar mitzvahs and engagement parties are also hosted.

Accommodation
Five wooden chalets in the park sleep up to 45 people, with beds, shower rooms and kitchenettes. A dormitory and extra tents can be added for larger groups. The chalets are booked as an option to the venue hire.
Catering
The estate works with the caterer Maison Depreytere, active for more than 40 years, which builds menus for each event and adapts them to dietary needs, vegan included. Other caterers are accepted under conditions. For seminars, the partner caterer covers breaks, standing lunches and dinners.
History and setting
The château was built in the 16th century and is listed as a historic monument. Its features include a wrought-iron gate, a horseshoe staircase on the park side, slate pepper-pot roofs, mullioned windows and salons with old paneling, marble fireplaces and herringbone parquet. The stables and outbuildings, in millstone and brick, frame the main courtyard. The park is entirely walled.
Getting there
The estate is on the D411 at Marolles-sur-Seine, close to exit 18 of the A5 motorway, about one hour from Paris and 20 minutes from Fontainebleau, between Melun, Montereau-Fault-Yonne and Sens. Parking is available inside the estate.
