Seminars and company events
Le Secret de l'Île is a 125 m² vaulted cellar on the Île Saint-Louis, at 9 quai de Bourbon in the 4th arrondissement of Paris. It holds 35 people in a conference layout and 100 at a cocktail, and is used for seminars, team buildings, cocktail evenings, private events and filming. The operator, the agency Paris Réception, says it has organised more than 200 company events a year here since 2018.
The space is made of three vaulted alcoves and a square room. That shape suits a morning of plenary talks in the square room and workshops in the alcoves, or a cocktail where groups settle in different corners. The room has a video projector, a sound system and Wi-Fi. The warm, intimate atmosphere of the stone vaults is the main argument for choosing it over a standard meeting room.
Rooms and capacities
The main hall is the only space listed: 125 m² with three vaulted alcoves, 35 people in conference layout, 100 people standing. For a seminar with fewer than 35 people, the agency has other rooms in Paris, such as the Cabinet d'Ingéniosité near Bastille in the 11th arrondissement, which seats up to 18, and the Caves Saint-Sabin, also in the 11th.
The room is bookable by the hour or for a longer period. Check access conditions when you request a quote, because the official pages do not describe stairs or step-free entry for a cellar.
Catering and activities
Paris Réception offers a cocktail service with a range of savory and sweet pieces, adapted to dietary needs such as vegan, halal and kosher. The agency designs its own team building activities, including escape games, giant escape games, murder parties, quizzes, karaoke, photobooths and 360 photobooths, and can run them in the cellar or elsewhere in the city. This is useful for a seminar that needs a break from the program, and the agency was created around escape games, first with Gamescape in 2014.
The agency also organises escape games for institutions, and the cellar can be filmed in for shoots.
History and setting
The Île Saint-Louis is a small island in the Seine behind Notre-Dame, known for its quiet quays and old houses. The venue sits on the Quai de Bourbon, which gives guests a short walk along the river before and after the event.
Getting there
The address is 9 quai de Bourbon, 75004 Paris. The official pages do not list stations. Pont Marie (line 7) is the closest metro station and Sully – Morland (line 7) is also within walking distance. Check the route with the agency before sending guests, as the island has no metro station of its own.
