Piazza del Plebiscito

Castel dell'Ovo ("Egg Castle") is a seafront castle in Naples, located on the former island of Megaride, now a peninsula, on the Gulf of Naples in Italy. The castle's name comes from a legend about the Roman poet Virgil, who had a reputation in the Middle Ages as a great sorcerer and predictor of the future.

Castel Nuovo (Italian: [kaˌstɛl ˈnwɔːvo]; Neapolitan: Castiello Nuovo; 'New Castle'), often called Maschio Angioino (Italian: [ˈmaskjo andʒoˈiːno]; Neapolitan: Maschio Angiuino; 'Angevin Keep'), is a medieval castle located in front of Piazza Municipio and the city hall (Palazzo San Giacomo) in central Naples, Campania, Italy. Its scenic location and imposing size makes the castle, first erected in 1279, one of the main architectural landmarks of the city.

The Royal Palace of Naples (Italian: Palazzo Reale di Napoli) is a historic building located in Piazza del Plebiscito, in the historic center of Naples, Italy. Although the main entrance is located in this square, there are other accesses to the complex, which also includes the gardens and the Teatro di San Carlo, from the Piazza Trieste e Trento, Piazza del Municipio and Via Acton.

The Real Teatro di San Carlo ("Royal Theatre of Saint Charles"), as originally named by the Bourbon monarchy but today known simply as the Teatro (di) San Carlo, is a historic opera house in Naples, Italy, connected to the Royal Palace and adjacent to the Piazza del Plebiscito. It is the oldest continuously active venue for opera in the world, having opened in 1737, decades before either Milan's La Scala or Venice's La Fenice.
