Castel dell’Ovo (in Italian, Egg Castle) is a seaside castle located on the former island of Megaride, now a peninsula, on the gulf of Naples in Italy. The castle’s name comes from a legend about the Roman poet Virgil, who had a reputation in medieval times as a great sorcerer. In the legend, Virgil put a magical egg into the foundations to support the fortifications. If something had broken the egg, the castle was destroyed and a series of disastrous events would have involved the city of Naples. The castle is located between the districts of San Fernando and Chiaia, opposite the zone Mergellina.
