Castel Nuovo (Maschio Angioino)
(1279-1282) - This castle was built by Charles of Anjou and re-built by Alphonsus I of Aragon. It has undergone various restorations in the course of the years to repair and preserve its original structures.
The Triumphal Arch, which commemorates the entry of Alphonsus I into Naples in 1443, is the outstanding product of several Renaissance sculptors.
Other interesting parts of the castle are the Cappella Palatina (Palatine Chapel) and the Sala dei Baroni (Baron's Hall), where the Naples town council meets.
