The Baroque church of San Carlo was built by the Barnabites in 1612. First closed in 1810 with the Napoleonic suppression of the adjoining convent, and then definitively closed with the unification of Italy, it was later used as a theatre. There is little news of its internal structure, which was perhaps no less rich than other Baroque churches in the city. However, it is certain that the sculptor Giuseppe Scaglia left his signature in the chapel of the Virgin of the Seven Sorrows. The fate of approximately 300 pieces is unknown, including paintings, furniture and sacred objects that made up the sumptuous furnishings. Restored several times, today, with its 230 seats, the theatre hosts theatre and cinema events and conferences.
