Golden stuccoes, wooden decorations, velvet and glass: the horseshoe-shaped auditiorium hosts up to up to 1300 people in the stalls, five floors of boxes and a gallery. Acoustically perfect, it is dominated by the so-called "Symbolic wheel" that forms its ceiling. The wheel resembles a wide flower with eleven petals. Each of them is part of the original cooling system of the theatre, as they can be opened to let the hot air flow out.
Beside the institutional musical events, the auditorium is the place of meetings, dinner and workshops.
