In short: Commissioned in 1279 by Charles I of Anjou, Castel Nuovo was designed to be a grand royal seat. Yet, due to the War of the Sicilian Vespers, the new palace remained unused by its founder, sitting empty until his death in 1285.

The origins of Castel Nuovo, also known as Maschio Angioino, are tied to the rise of the House of Anjou. After defeating the Hohenstaufens in 1266, Charles I of Anjou moved the Sicilian capital from Palermo to Naples. Seeking a residence more suitable than the existing Norman fortress, Castel Capuano, he commissioned French architect Pierre de Chaulnes to design a magnificent palace near the sea. Construction began in 1279 and was completed in just three years, an exceptionally rapid pace for the 13th century.

The castle's history is defined by political upheaval and architectural transformation. While it served as a royal seat for the kings of Naples, Aragon, and Spain until 1815, it was frequently a site of conflict. In 1347, Joanna I of Naples was forced to undergo radical restructuring after the castle was looted by the army of Louis I of Hungary. Later, in 1443, Alfonso V of Aragon completely rebuilt the fortress in the Catalan Gothic style, employing the architect Guillem Sagrera. This reconstruction added the five large cylindrical towers that define its silhouette today.

Beyond its defensive and royal functions, the castle has been a stage for significant historical moments. In December 1294, the Main Hall hosted the abdication of Pope Celestine V and the subsequent election of Pope Boniface VIII. In 1486, the Hall of the Barons became the site of a decisive trap set by King Ferdinand I of Naples, who lured conspirators to a wedding party only to arrest them, effectively ending the Conspiracy of the Barons and centralizing royal power.
