The Château de Tresserve hosts general meetings, company seminars, product launches, graduation ceremonies, company evenings, weddings and private parties. The main floor seats up to 220 guests or 300 in conference style, the terrace takes cocktails for up to 500, and 12 rooms and suites sleep 40. The château stands on the shore of Lac du Bourget in Tresserve, in Savoie, next to Aix-les-Bains.
Seminars and company events
Companies can book the château for a weekday, several days or an exclusive weekend, all year round. On the main level, the Salle du Lac and the veranda form a single 330 m² space with a lake view, set up for up to 220 seated guests or 300 in conference style. On the lower level, several rooms work as breakout spaces for workshops. The veranda can be turned into a car showroom for a launch.
Technical equipment is included: Wi-Fi, sound on both levels, giant 4K screens, wireless microphones, stage, lighting and outdoor lighting. A technician is on call throughout the event, a manager stays on site and a host greets guests. The private parking holds 40 cars under video surveillance, and the public Lido car park, 100 meters away, has more than 300 spaces.
Weddings and receptions
For a wedding, the exclusive formula gives access from Friday 6 p.m. to Sunday 5 p.m., with the 12 rooms available from the Friday evening. The ceremony can take place in the one-hectare park, among old trees, ornamental pools and a gazebo. Drinks follow on the terraces or in the veranda if it rains, dinner in the Salle du Lac, and the party moves to the lower level, with its bar and dance floor. A children's room with a video corner can be staffed by babysitters, and a brunch can be served the next day. Planners Camille and Lou-Ann follow couples from the first visit.
Rooms and capacities
The upper level holds the Salle du Lac (220 m², up to 150 seated) and the veranda (110 m², often used for the dance floor). Combined with the lower level, the château seats up to 220. The lower level has a 46 m² entrance hall, the 100 m² Salle Cuvage, the 37 m² vaulted room used as a smoking lounge, and the 100 m² Club du Château with bar and dance floor. The park adds a 450 m² terrace and an outdoor area called the Place du Village. A marquee or stretch tent can be added in bad weather.
Accommodation
The château has 12 rooms and suites sleeping up to 40 guests: five on the first floor, including the Victoria suite with lake view and hammam shower, and seven on the second floor facing the lake or the park. Rooms have air conditioning, a safe, a coffee machine and Clarins toiletries. A continental breakfast is served in the breakfast room, which has its own terrace.
Catering
The château does not cook: you choose your caterer, who works in a fully equipped kitchen. The team suggests caterers, florists, decorators and photographers who know the site, with no obligation to use them. Tables, chairs, 30 covered high tables and buffet tables are set up by the staff, and cleaning is included except for the kitchen.
History and setting
The estate is recorded in 1344, and the Château de Bonport was built in 1584. In the 19th century it became a fashionable inn for spa visitors from Aix-les-Bains. A fire destroyed it in 2008. Nicolas Tournier, a Courchevel hotelier who grew up in the château, bought it back in 2013 and rebuilt it over several years; it reopened for events in 2021.
Getting there
The address is 205 Bord du Lac, 73100 Tresserve, on the lakeshore road just south of Aix-les-Bains. Parking is on site, with overflow at the Lido car park nearby.
