Designed in 1878 by architect Nicolò Bruno, the building is an imposing Eclectic-style structure, featuring an elegant, delicate exterior that has an almost neo-Renaissance appearance.

The Rossetti theatre is located just before the hill on Viale XX Settembre, compelling the architect to design the main façade to follow a steep slope.

The theatre activities are held in two rooms: the smaller Bartoli Room has 128 seats and is used for contemporary dramas, while the Large Room, Sala Assicurazioni Generali, has a seating capacity of 1530.
