In Naples, Castel Nuovo closed to the public on September 1 and 2, 2026

Closure announced for works

The Comune di Napoli’s official page says that Castel Nuovo will be closed to the public on September 1 and 2, 2026, because of works.

The same page says that additional closures may take place in the following days and asks visitors to check the page for updates.

Check the official page before visiting

The closure concerns access to the monument; the municipality’s information does not provide a detailed calendar for possible later closures.

The same site presents Castel Nuovo as a cultural complex that includes, among other things, the Museo Civico and exhibitions, so access should still be checked before travelling.

Usual opening hours to check

Outside the announced closures, the official page lists opening from Monday to Saturday, 9 a.m. to 6 p.m., with last entry at 5:30 p.m.; the monument is closed on Sunday.

A monument whose page recalls its history

The presentation of Castel Nuovo recalls that, in the time of Robert of Anjou, the castle was a cultural centre frequented in particular by Giotto, Petrarch, and Boccaccio. It then refers to the Aragonese and the reconstruction works undertaken by Alfonso I.

The page also describes the Triumphal Arch erected between the Torre di Mezzo and the Torre di Guardia to celebrate Alfonso I’s victorious entry into the city. It places this work within a transformation of the medieval castle-palace into a fortress suited to the military requirements of the modern era.

The monument is presented as a trapezoidal construction, formed by a tuff curtain wall into which five cylindrical towers are set. Four of these towers are made of piperno and one of tuff, on a base containing wall walks.

Successive uses leading to today’s cultural role

After the Aragonese, the page indicates that the French succeeded them for a limited period, before the arrival of the Spanish and Austrian viceroys. During the viceregal period, between 1503 and 1734, the defensive structures of the castle, then mainly military in purpose, were further altered.

With the accession of Charles III of Bourbon in 1734, the castle was gradually surrounded by buildings, depots, and homes. At the beginning of the 20th century, the municipality undertook work to separate the castle from adjoining constructions, recognising its historical and monumental value.

Today, the complex is intended for cultural use and includes the Museo Civico. The listed route includes the Sala dell’Armeria, the Cappella Palatina or di Santa Barbara, the first and second floors of the southern curtain wall, as well as the Sala Carlo V and Sala della Loggia for exhibitions and cultural initiatives.
