The Château de la Plumasserie can host seminars, executive committees, training days, gala dinners, team-building days and weddings across five independent reception spaces, the largest covering 700 square meters. The 17th-century château stands in a 25-hectare park at Fontenay-Trésigny, in Seine-et-Marne, about 50 minutes from Paris. It was fully renovated in 2025.
Seminars and company events
The estate sells seminars, conferences, executive committee meetings, training sessions and study days, as well as product launches, end-of-year parties and gala evenings. Meeting rooms can be set up for a meeting, a conference, a workshop or a presentation, with a stage, projection, round tables or theater seating. Each space has its own entrance and its own parking, so two groups can work on the estate without crossing paths.
For team building, the estate suggests a treasure hunt, outdoor games, water games, crafts and an escape game, using the park, the forest, the ponds and the pools. For an evening event, the château can be lit in company colors, and a dinner or an awards ceremony can take place in the château hall, under the Verrière or in another space. Gardens, bar areas, terraces and barbecue corners are available for the rest of the evening.
No supplier is imposed. The team can coordinate the day itself, and earlier access and adjusted hours are possible depending on availability.
Weddings and receptions
Weddings, ceremonies (secular, religious or civil) and private celebrations are a large part of the estate's activity. Couples can use one space or combine several: one for the ceremony, one for dinner, one for children and one for the next-day brunch. A coordinator can run the wedding day and liaise with the couple's suppliers. Depending on availability, access the day before or on the morning of the event is offered at no extra charge. The château can also be booked whole, with its hall, grounds and bedrooms.
Rooms and capacities
The estate lists five independent reception spaces. Each has an equipped catering kitchen, its own access and its own outdoor area.
La Verrière covers 700 square meters, with timber structures, wide glazed bays and adjoining terraces suited to cocktails. L'Orangerie covers 530 square meters, with chandeliers, and opens onto a pool and a flower garden. The Salle du Château, inside the château itself, offers more than 250 square meters with moldings and chandeliers, and bedrooms on the floor above. Le Prieuré covers more than 300 square meters, has a glass floor set with natural flowers and opens onto a fenced pond. La Bambouseraie offers more than 500 square meters with a glass floor, a pool and a large garden.
The site does not publish guest numbers per room, so confirm the seated and standing capacity for your layout with the team.
Accommodation
Guests can stay on site in two kinds of lodging: bedrooms on the upper floor of the château, some with a balcony over the park, and independent chalets in the park, each sleeping up to six people with a private terrace. Breakfast and brunch can be arranged. Leisure facilities include an outdoor pool, a hot tub, forest walks and a volleyball court. The total number of beds is not published.
Catering
The estate does not impose a caterer. Every reception space has a fully equipped catering kitchen, so the caterer of your choice can work on site.
History and setting
The château dates from the 17th century and stands on the site of an earlier fortress. The 25-hectare grounds combine landscaped gardens, ponds, pools, woodland and fields.
