Castle Castel Nuovo in Naples

You're standing at Castel Nuovo in Naples, right by the harbour and next to the city hall on Piazza Municipio. Look at those five fat round towers. The name means New Castle, but that's relative: it was meant to set it apart from the city's two older castles, Castel Capuano and Castel dell'Ovo. Locals also call it the Maschio Angioino, the Angevin Keep.
