Theatre ''all'italiana'' with a ''U'' shaped hall with two tiers of boxes and a gallery, with a capacity of 375 seats.
The theatre has an eighteenth-century origin, (it was opened in 1774), but the actual aspect is due to the 1890 amplification, of which the recent restructuring maintained the formulation.
Keep name of the banker Gaetano Bonoris who financed the expansion of end '800 to get round the administration and take possession of the ancient fortress town, where he then build his noble dwelling.
