Together with the adjacent
Certosa di San Martino, this forms an important group of buildings situated
on the hill on which the quarter of Vomero has grown up. Castel Sant'Elmo was also built on the orders of Charles of Anjou: its
construction, in tuff, was begun in 1329 and completed in 1343 by
the work of the architects Tino da Camaino, Atanasio Primario and Francesco di
Vito.
The building, whose architectural features from a distance resemble those of the
Castel dell'Ovo, was one of the city's fortifications and was used
above all to protect it from invasions from the sea.
It was built where the Normans, in 1170, had a fort called Belforte
surrounded by rich vegetation.
All Naples' historic events involve Castel Sant'Elmo.
The King Charles V, through the viceroy Pedro de Toledo, rebuilt completely the
castle by the work of the Spanish architect Pier Luigi Scribā, that designed the
star-shaped plan of the castle.
It has witnessed numerous sieges, fierce disputes between the various dominating
powers, and repeated popular uprisings, including the now legendary Masaniello
revolt of 1647.
The old fort has risked destruction several times.
During the Second World War the Germans had intended to blow it up before they
left the city, changing their minds only at the last minute.
The castle, which has now been restored, having been freed from its use as a
military prison, houses exhibitions of art and history and also contains the
Molaioli Library of Art and a videotheque which supplies information
on all of the city's monuments.
The complex also contains the 16th centuryChurch of Sant'Elmo and
the Chapel of Santa Maria del Pilar (17th century).
From the communication trenches and the Castle's upper square there is an
extensive view over the city and Vesuvius, the Neapolitan plain, and the
marvellous gulf bounded by Capri and the profile of the Phlegraen
islands.
It is worthy to visit the Church of St. Erasmo that has a rich floor in
maiolica and tile. Behind the altar there is the tomb of Pietro de Toledo, a
viceroy's relative and first lord of St. Elmo.
In front of the entrance of the church there are the prisons where were
imprisoned, among many others : the Princess Giovanna di Capua, Tommaso
Campanella, Angelo Carasale the architect of the San Carlo theatre and many
revolutionaries: Mario Pagano, Domenico Cirillo, Gennaro Sessa di Cassano,
Francesco Pignatelli, the Count Ettore Carafa, Luigia Sanfelice, Pietro
Colletta, Carlo Poerio, Silvio Spaventa and many others.
