The fortified Ovo (or “egg”) Castle stands on the island of Megaris, a port created by the inhabitants of ancient Parthenope. The common legend explaining the name is that when the Roman poet Virgil stayed here in the 1st century B.C.E., he buried an egg in the ground and declared that when it broke, disaster would befall the city. Completely covering the little island, the castle is a romantic and breezy spot. Views from the ramparts are magnificent.
