Hôtel Le Marois can host general assemblies, conferences, product launches, gala dinners, cocktail receptions and weddings, with eight salons that together take more than 600 guests. The mansion stands at 9-11 avenue Franklin-D.-Roosevelt in the 8th arrondissement of Paris, a short walk from the Champs-Élysées, and its terrace looks toward the Grand Palais.
Seminars and company events
The first floor is the professional heart of the house: a suite of four salons, Bolivar, Washington, Lafayette and Montcalm, which together offer about 300 m² with 18th-century decor, high ceilings, natural light and air conditioning. These rooms suit plenary sessions, shareholder meetings, press conferences and seated galas. The lower levels hold salons and a library with contemporary furniture, better suited to study days, workshops and committee meetings for smaller groups. The venue also lists fashion shows, morning conferences followed by a private lunch, and culinary workshops among the formats it handles.
Espace Franklin, set in the former baths in the basement, is presented as a room for conferences and evening events, without fixed closing hours or volume limits. That makes it useful for a party after a daytime program.
Weddings and receptions
Weddings, ceremonies, birthdays and commemorations are part of the private offer. Couples can use the grand staircase, with its carved woodwork and a ceiling painted on the theme of the Apotheosis of Psyche, for photographs, then move between the salons and the furnished terrace for drinks and dinner. The whole house covers 850 m² over three levels.
Rooms and capacities
The house counts eight modular salons. On the ground floor, Le Lobby (90 m²) opens onto the terrace, and Espace Club (55 m²), which includes Salon Jefferson (28 m²), looks out over it. On the first floor, Salon Washington (93 m², two large windows), Salon Montcalm (70 m²), Salon Lafayette (61 m²) and Salon Bolivar run in sequence. Espace Franklin occupies the basement. The venue gives a total capacity of more than 600 people but publishes no figure per room, so layouts are worked out with the events team.
Catering
Food and drink are handled by Butard Enescot, an independent Paris event caterer founded in 1933. It covers cocktails and seated lunches and dinners, and the pastry team can prepare vegan desserts on request.
History and setting
The architect Henri Parent built the mansion in 1863 for Comte Le Marois, son of one of Napoleon's generals. It is also known as the Hôtel de Ganay. In the 19th century its salon drew writers and intellectuals, and it stands on the site of a former home of Marie Duplessis, the woman who inspired Alexandre Dumas fils to write La Dame aux camélias. Since 1927 it has been the seat of the Association France-Amériques, and several rooms carry the names of American figures such as Washington, Jefferson and Franklin.
Getting there
The house sits between the Rond-Point des Champs-Élysées and the Seine. Franklin D. Roosevelt metro station, on lines 1 and 9, is a few minutes away on foot, and line 1 runs directly to Gare de Lyon and to La Défense, which helps for guests arriving by train or from business districts.
