The Castel Sant’Elmo is a fortress in Napoli, Italy located on a high mountain (the Vomero) and therefore it is maybe the best viewpoint in the city. It was built in 1329 and was used from 1860 to 1952 as a military prison. Since 1982 it is open to the public.
Even if you don’t want to visit the fortress it is worth getting up here and enjoying the views. Afterwards you can have a walk down the hill – but be warned: back to Piazza Garibaldi or anywhere in the center of the city it is really a long walk.
