The hill of Vomero has seen the construction of Castel Sant’Elmo built on the site of a former Angevin medieval watchtower.
The superb view over the city, the Bay of Naples and the Vesuvius, which can be enjoyed from the terrace of the castle, is worth the trip.
The area is easily reached by the funicular or metro from various places in the lower city: Piazza Dante, Piazza Municipio and Chiai.
