The Teatro della Pergola opened in 1656. It is considered as the oldest theatre in Italy and it was once the private theatre of the grand dukes. The theatre does have two halls; smaller programs take place in the 400 seat Saloncino, a former ballroom with superior acoustics. It is often specifically chosen by vocalists for its magnificent sound. There is a plaque commemorating the premiere of Verdi's Macbeth in 1847.
