If only the walls of Castel Capuano could talk! But seeing they can't, check if tours are available to hear some of its tales instead.
When you've finished exploring this Naples City Centre fortified complex, why not check out Herculaneum, Castel dell'Ovo, and Stadio Diego Armando Maradona? They're not too far from Castel Capuano and also a favorite with tourists.
