Castel Nuovo, often called Maschio Angioino, is a medieval castle located in front of Piazza Municipio and the city hall (Palazzo San Giacomo) in central Naples, Italy. Its scenic location and imposing size makes the castle, first erected in 1279, one of the main architectural landmarks of the city.
Before the accession of Charles I of Naples (Charles of Anjou) to the throne in 1266, the capital of the Kingdom of Naples was Palermo. There was a royal residence in Naples, at the Castel Capuano. However, when the capital was moved to Naples, Charles ordered a new castle, not far from the sea, built to house the court. Works, directed by French architects, began in 1279 and were completed three years later.
Due to the War of the Sicilian Vespers, the new fortress remained uninhabited until 1285, when Charles died and was succeeded by his son, Charles II. Castel Nuovo soon became the nucleus of the historical center of the city, and was often the site of famous events. For example, on December 13, 1294, Pope Celestine V resigned as pope in a hall of the castle. Eleven days later, Boniface VIII was elected pope here by the cardinal collegium and immediately moved to Rome to avoid the Angevin authority.
