Castel Nuovo, often called Maschio Angioino (Italian: "Angevin Keep"), is a medieval castle located in front of Piazza Municipio and the city hall (Palazzo San Giacomo) in central Naples, Italy. Its scenic location and imposing size make the castle, first erected in 1279, one of the main architectural landmarks of the city. It was a royal seat for kings of Naples, Aragon and Spain until 1815.
The Castle has a complex structure, part of which was rebuilt, after several dominations, by Alfonso of Aragon. Today, they remain only the Palatine chapel, some towers and the walls, but the Castle had originally a trapezoidal plant, five big protection towers, a moat that surrounded it, a Catalan staircase inside each tower and, between the two towers that protected the entrance (also called towers ‘Di Mezzo’ and ‘di Guardia’), a marble triumph arch. In particular, among the most important elements that are arrived until us, there is the ‘Palatine Chapel’, also called church of ‘San Sebastiano’ or of ‘Santa Barbara’, characterized by a gothic architecture and inside magnificently frescoed with artworks by Masi di Bianco and even Giotto. Moreover, the Maschio Angioino is also known for some stories such as the legend of the crocodile, one of the most famous Neapolitan legends. According to the legend, this crocodile was brought to Naples from Egypt and, in particular, by the Queen Joanna II who married James of Bourbon. It seems that she made eat her lovers to the crocodile so that her husband could not discover them.
