Castel Nuovo (Maschio Angioino), Naples

Castel Nuovo, popularly known as the Maschio Angioino, is the most architecturally striking landmark of the Naples waterfront in Campania, Italy. Built between 1279 and 1282 for Charles I of Anjou as a new residence distinct from Castel dell'Ovo, the castle's five massive cylindrical towers of dark volcanic tufa rise above the port and the Piazza Municipio, creating a dramatic silhouette visible across the Bay of Naples. The most celebrated architectural feature is the Triumphal Arch of Alfonso of Aragon, inserted between the two main western towers between 1453 and 1467 following the Aragonese conquest of Naples—a masterpiece of Renaissance sculpture celebrating Alfonso's entry into Naples in 1443, with two superimposed arches richly carved with battle scenes, river gods, and allegorical figures in white marble that contrast strikingly with the dark tufa towers flanking them. The castle served as the seat of the Angevin and later Aragonese kings of Naples and as the administrative centre of the Kingdom of Naples through the medieval and early modern periods. The interior is now home to the Museo Civico, distributed across the ground floor and the Gothic-vaulted Palatine Chapel, which contains important medieval frescoes attributed to followers of Giotto and 14th–15th-century sculptures. The Sala dei Baroni (Hall of the Barons), named for the eight barons summarily executed here by Ferrante I of Aragon in 1486, is the castle's principal hall and features a Gothic star-vault roof of exceptional quality. Views from the castle towers across the waterfront and bay toward Vesuvius are outstanding.
