The Teatro Comunale Garibaldi is composed of a Sala Grande, capable of accommodating 490 spectators, and of a Ridotto, for 60 spectators. The foyer hosts, in addition to the ticket office and cloakroom, the theater bar.

The Sala Grande, a classic example of nineteenth-century Italian theater, has four tiers of boxes and an auditorium in the warm colors of red, velvet, with gilded finishes and stuccos. The stage with a proscenium of about 7.5 meters wide and a depth of over 11 meters is suitable for plays, concert performances as well as conferences and company presentations.

The Ridotto, located on the first floor of the Theatre, has an audience and a stage suitable for small events and meetings which replicate, albeit on a smaller scale, the classic and elegant atmosphere of the Sala Grande.
