La Garnison hosts meetings, management committees, training days, team building, product launches and small weddings for up to 50 seated guests, or 60 for a cocktail. The venue is a 17th-century manor with more than one hectare of enclosed grounds in Orvault, on the northern edge of the Nantes metropolitan area, about 10 minutes from Nantes.
Seminars and company events
The estate sells room hire, per-person packages and a turnkey day built around the whole site. Groups have the property to themselves during their event. The meeting room comes with a projection screen, a video projector, Wi-Fi, a flipchart, tables and chairs; the wedding page also lists a laser projector and a sound system. Outdoor furniture includes bistro tables, low tables with armchairs and large parasols, so breakouts can move into the garden in good weather. A bar list of soft drinks, beer, wine and champagne is available. The enclosed private car park holds 30 cars and has a charging point for electric vehicles. The owners also publish lists of partners for activities and services.
Weddings and receptions
The manor hosts weddings, christenings, family gatherings and end-of-year parties. The format suits an intimate wedding or a confidential ceremony rather than a large banquet. The team can help organize the day, and the site lists recommended suppliers for catering, decoration and communication. Guests can stay on site in the four guest rooms, and more beds are available nearby with partner hosts.
Rooms and capacities
The Jules Verne reception room measures 60 square meters and holds 50 seated guests or 60 standing. A covered open-sided area, the préau, extends the room and stays usable in rain. Inside the main house, the Salon Garnison is a quiet, light room with a large fireplace for small meetings of up to 10 people. Outside, a terrace opens onto an adjoining lawn for receptions, and the landscaped park can host outdoor activities.
Accommodation
Four guest rooms sleep up to 12 people. Dragon, on the first floor, measures 24 square meters and faces west over the park. Garnison, the signature room on the first floor, has a fireplace. Cens, under the roof on the second floor, measures 24 square meters. Jules, also on the second floor, is the largest at 34 square meters. Rooms can be booked online outside events.
Catering
There is no in-house restaurant. The site lists partner caterers: Traiteur Le Bot, the restaurant Le Pavillon, which also caters private and corporate events, and the butcher and charcuterie maker L'Effet Bœuf. The per-person packages and turnkey day are quoted on request.
History and setting
Written records mention the manor in 1604. The property came from the division of a larger estate, and Guillaume Lemarie took the title of lord of La Garnison in 1616. His family, ennobled through the Chamber of Accounts of Brittany, stayed until 1790. A granite staircase inside is known locally as the Dragons' staircase. Around 1900 the house was in poor condition and was nearly demolished before farmers bought it.
Getting there
The manor is at 13 chemin de la Garnison in Orvault, about 10 minutes by car from Nantes. Parking for 30 cars is on site.
