Castel dell'Ovo (Italian: "Egg Castle") is located on a small island, the Megarides, where colonists from Cumae founded the original nucleus of the city in the 6th century BCE. In the 1800s a small fishing village (Borgo Marinari) sprung-up around the castle's southern wall. This village still stands. However, it is now more known for its marina and several fine restaurants.
The castle is connected by a small causeway that is a popular place for newlyweds to have their wedding photos taken.
The castle's name stems from a medieval legend which holds that the poet Virgil, who developed a medieval reputation as a great sorcerer, had a magical egg put in the foundations to support them. Its location affords it an excellent view of the Naples waterfront and the surrounding area.
