Porta bronzea

Porta bronzea is the bronze entrance gate of Castel Nuovo in Naples, cast between 1465 and 1475. It commemorates King Ferdinand I of Naples and his victory in the 1459–1463 war against rebellious barons and the claimant Jean de Anjou. Probably inspired by Ghiberti’s Gates of Paradise and Filarete’s door for St. Peter’s Basilica, it was designed as the entrance to the triumphal arch of Castel Nuovo. The gate is made up of four panels, each measuring 130 x 120 cm, with two semicircular lunettes above them. Its reliefs depict episodes from the war, framed by classical friezes and accompanied by Latin couplets.

History and restoration

Late damage dateLate 15th century
Alternative damage explanationSome authors attributed the damage to the 1503 attack on Castel Nuovo by Gonzalo Fernández de Córdoba during the Naples War of 1501–1504
Assessment of alternative damage explanationThis theory is considered improbable because the cannonball appears to have struck from inside the gate and is smaller than the usual caliber for such a confrontation
Historical fateAfter Charles VIII conquered Naples in 1495, the gate was dismantled and shipped toward France
Damage hypothesisThe gate was probably on the deck of the French ship when a cannonball struck it during a battle with the Genoese fleet, becoming embedded in the door
Subsequent fateThe Genoese reportedly sent it back to Naples in 1495, and it was reinstalled in its place
