Foyer 850 offers an architectural space and line for hosting poster sessions, cocktails and a place for social interaction against a tailored backdrop. Its maximum hosting capacity is 900 persons in its cocktail format.

The bar furniture and mosaic carpet is a work created by the artist Benjamin Dufour and architect-designers Guillaume Eckly and Barbara Fischer, designed in the context of the 1% artistic contribution*.

*The 1% artistic contribution is a legal obligation that promotes the creation of works of art for the decoration of public buildings. It requires contracting authorities to set aside 1 % of the total cost of their constructions for ordering or acquiring works of art specially designed for the building.
