The Great Hall is the theatre’s historical auditorium, with the capacity to seat 833 spectators. The 23-metre-high stage accommodates any kind of performance, and has an orchestra pit with a Spiralift platform lift. The seating area consists of the stalls, stalls boxes, first-floor boxes, dress circle, upper circle, balcony and upper gallery.

Directly above the main entrance on the second floor is the Salon and Cafetería area, adjacent but independent spaces connected by a small access way. The Cafetería has three large windows to the outside and a bar. The Salon, fitted with three Murano-glass ceiling lamps, has direct access to the Cuesta del Principal and accommodates 90 people.

Espai Zero is the antechamber, which accesses the Small Hall via a wide staircase and a lift. The space is lit with natural light, has an irregular perimeter and accommodates 80 people.

Situated on the fifth level above the stalls in the Great Hall, the Small Hall seats 144 spectators in a completely open space with the capacity to adapt to different tiered seating and stage setups.
