Over the centuries, the fortress was partially destroyed due to several events such as an earthquake during the 14thcentury or the French and Spanish attacks during the 16th century. In the 19th century, Naples underwent a massive period of urban restructuring, during which time the castle was meant for destruction but was left to disrepair instead.
Today, the castle is open to visitors following extensive renovations in the late 20th century. Its largest rooms are now used for exhibitions and conventions both private and public. Nearby on the coast, in the Borgo Marinari, there are several restaurants and bars that visitors can enjoy.
