Attend the opera in Toscanini's home-town theater (plus, Verdi hails from nearby)
Parma's opera house, the Teatro di Regio, is not too far down the scale of high regard from Milan's La Scala. After all, Verdi was born nearby and Arturo Toscanini, who often conducted at the theater, is a native son.
Tickets can be hard to come by, since they're swallowed up for the entire October-March season well in advance by opera buffs from across the region.
However, the tourist office sometimes sells standing-room-only tickets. You should also check the box office at Strada Garibaldi 16A, near Piazza della Pace, for last-minute cancellations.
