In Roman times, Lucullo built a large fortified villa on the sea there, where in 476 AD the last emperor Romulus Augustulus was exiled. Known in the Middle Ages as the islet of San Salvatore, it was also occupied by the Saracens. In the 12th century Roger the Norman established his residence there, then Frederick II made it the Reggia of the Swabian rulers that guarded the royal treasure. In the Angevin era, borrowed from the legend of Virgil Mago's egg, the name Castel dell’Ovo was established and then became impregnable with the Aragonese restructuring. A military function that remained until the Renaissance. After the restoration in 1975 it is now a congress center and museum space. Outside, on the islet connected to the city by an artificial isthmus, Borgo Marinari extends with renowned nautical clubs, bars and restaurants.
