Castel dell'Ovo, also known as Egg Castle, is a castle and an important landmark located on an islet in the Bay of Naples. Its name comes from a legend about the Roman poet Virgil, who, in the Middle Ages, was regarded as a powerful sorcerer and was said to have placed an egg in the castle's fortifications to make them stronger.

In the Renaissance, a drydock was located nearby which housed Cesare Borgia's naval cannon, but in 1502, the Assassin Ezio Auditore destroyed the only prototype of the vehicle.


A medieval castle located on the former island of Megaride, the Castel dell'Ovo is named for a legendary Roman poet who was believed to be a great sorcerer. Legend tells us that he placed a magical egg in the structure's foundation to support it.

The original edifice was a fortified villa where the last Roman Emperor, Romulus Augustus, was exiled in 476.
