Château de Nanterre, run by United Kitchens, hosts seminars, evenings, afterwork events, product launches and team building for companies, with up to 400 guests at a cocktail. The venue combines three modular meeting rooms, a reception space, two terraces and a garden in Nanterre, 15 minutes from the Étoile in Paris.
Seminars and company events
The seminar space is made of three equipped rooms, Menthe Citron, Menthe Bergamote and Menthe Poivrée. Removable partitions let you join several rooms or create one continuous space. The official site gives 270 m² and 215 seated for the seminar offer. A separate reception area handles breaks, cocktails and lunches, with access to the terrace and the garden.
For evenings, the venue offers 500 m² of modular space and 400 guests at a cocktail. An afterwork uses the 270 m² indoor area and two terraces, one of them covered, for 250 guests at a cocktail. Product launches can use between 50 and 500 m² of modular space, again up to 400 at a cocktail.
Team building is also sold on site, with eight activities built around responsible food. The garden includes a permaculture vegetable plot.
Weddings and receptions
The official pages describe a corporate offer only. They do not present weddings, so this venue should be treated as a place for company events, evenings and client receptions.
Rooms and capacities
The reception space is 230 m² according to its own description, with 150 guests at a cocktail and 90 seated, and two terraces. For meals, the site gives up to 90 people inside, 60 on the terrace and 25 on the covered terrace. The three Menthe rooms can be used separately or together.
Accommodation
The pages read do not mention overnight rooms. Plan accommodation separately in the Nanterre and La Défense area.
Catering
Catering is in house. United Kitchens runs a responsible caterer with seasonal products, a menu where half of the pieces are vegetarian, zero-waste service and a decision not to use beef, veal, salmon or avocado. The company received an A+ score on the FairScore Événementiel in 2026. The venue also hosts a 600 m² Foodlab of shared professional kitchens used by local artisans.
History and setting
The building dates from 1900 and was a toothpaste factory. It now houses responsible companies, which gives the place its identity. Terraces with shade, a garden and a vegetable plot complete the setting. The site reports between 250 and 400 events a year, depending on the page.
Getting there
The venue is on the Allée des Parfumeurs, by Rue Becquet, in Nanterre. The official site places it 15 minutes from the Place de l'Étoile in Paris and has a section with access directions.
