The Auditorium is the most elegant and biggest capacity room in the building. Overall, there is seating for 2,027 people divided between two levels; the orchestra pit and the amphitheatre. Both levels enjoy the same facilities although the amphitheatre can be partitioned off from the rest of the room by way of a large separating panel.

The room is furnished with exclusively designed seating, workstations, connections for computers and electricity installations, as well as state of the art audio-visual equipment, with Dolby surround sound and a cinema projector.
