As it stood in 1601
The shape it held in its prime.
Massive hexagonal-star fortress of pale volcanic tufa standing on a wooded hilltop, with six angular bastions and high, straight curtain walls pierced by rows of embrasures. A taller rectangular central block rises above the inner courtyard; the outer faces are mostly blank masonry punctuated by gun-ports and a single principal entrance topped by a carved inscription and imperial coat-of-arms. The fortress dominates the skyline above terraces of trees and the dense city below.
Its story
The story of Castel Sant'Elmo.
Documents record a structure on Vomero Hill from 1275, in the era of Charles of Anjou. Known originally as Belforte, it was likely a fortified residence with a gate marked by two turrets. In 1329 King Robert of Naples enlarged it to designs by the Sienese architect Tino da Camaino, who also supervised the adjacent Carthusian monastery of San Martino; by 1336 the palace was being described as a castle, and work continued after Camaino's death in 1343 under Attanasio Primario and Francesco di Vico.
The name Sant'Elmo derives from a former 10th-century church of Sant'Erasmo, worn down to 'Ermo' and finally 'Elmo'; by 1348 the building was called castrum Sancti Erasmi. The Angevin fortress was severely damaged by an earthquake in 1456. Overlooking Naples beside the Certosa di San Martino, it now serves as a museum, exhibition hall and offices.
