The theatre auditorium can also host conferences or congresses and offers seating for 1,600 on two levels: the stalls and the balcony.

Its foyers, spread over four levels allow for the organisation of coffee breaks or premium aperitifs. The last level has a terrace and offers a magnificent view of the Beaulieu gardens, the Alps and Lausanne Cathedral. The theatre areas are accessible through the main entrance or from the car park, and also directly from the adjoining congress areas.
