Castel Nuovo, also called Maschio Angioino or Mastio Angioino, is a historic medieval and Renaissance castle, as well as one of the symbols of the city of Naples.
The castle dominates the scenic Piazza Municipio and is the headquarters of the Neapolitan Society for the History of the Fatherland and the Naples Committee of the Institute of History of the Italian Risorgimento, located on the premises of the SNSP. The complex also houses the Civic Museum, which includes the Palatine Chapel and the museum itineraries on the first and second floors. The Valenzi Foundation has its representative office there.
