Welcome to Castel dell'Ovo, the oldest castle in Naples, standing proudly on the seafront of the Gulf of Naples. Situated between the San Ferdinando and Chiaia districts on the former island of Megaride, this striking rectangular fortress faces Mergellina across the water. You will love exploring a site rich with history that traces back to Greek settlers around 650 B.C. and Roman patricians.
According to local legend, the Roman poet Virgil placed a magical egg within the foundations to support its walls—warning that if the egg broke, the castle and Naples would suffer catastrophic ruin. As you visit, you can stroll across the 100-meter causeway overlooked by a high bastion, a favorite spot for newlyweds taking photos. Today, the castle's historical buildings house spaces for exhibitions and cultural events.
You will also see traces of its medieval past, when Normans, Aragonese rulers, and historic prisoners filled its halls, as well as the adjacent Borgo Marinaro, a former fishing settlement that now features a bustling marina and restaurants. Beneath the surrounding waters lie submerged ancient ruins, including a 2,500-year-old Greek harbor, making your trip here an unforgettable step into Neapolitan history.
