Castel Nuovo, better known in Naples as the Maschio Angioino, is the five-towered castle overlooking the port beside Piazza Municipio. Its name means “New Castle”: new, that is, when construction began in 1279 under Charles I of Anjou. Built as a royal residence, it remains a landmark in the thick of the city rather than a fortress isolated from it.
The castle took much of its present form under Alfonso V of Aragon, who conquered Naples in 1442. Between two of the massive towers stands the Renaissance Triumphal Arch, a marble celebration of his arrival, with sculpture by artists including Francesco Laurana and Pietro da Milano. Inside, the vaulted Sala dei Baroni recalls the building’s centuries as a royal court and a stage for Neapolitan politics.
A visit brings together architecture and art: the Museo Civico displays works from several centuries, while the Cappella Palatina preserves traces of the medieval castle. When accessible, the upper levels offer views across the harbour and Bay of Naples towards Vesuvius. The Teatro San Carlo, Galleria Umberto I and Royal Palace are all close enough to combine with a visit.
Check current opening hours, ticket details and access to individual rooms before setting out, as closures can occur for events. Municipio metro station is near the castle entrance, making public transport easier than driving into the centre. Wear comfortable shoes with good grip for the uneven stone surfaces and passages.
