The Real Teatro di San Carlo (Royal Theatre of Saint Charles) is located adjacent to the central Piazza del Plebiscito, and connected to the Royal Palace. It is the oldest continuously active venue for public opera in the world, opening in 1737, decades before both the Milan's La Scala and Venice's La Fenice theatres. The construction was ordered by Bourbon King Charles III of Naples. Given its size, structure and antiquity, it was the model for theatres that were later built in Europe.
