Castello Grande / Castello Svevo
The Holy Roman Emperor, Frederick II, founded this imposing complex of fortifications which served as the imperial residence, prison, arsenal and garrison. A succession of kings and emperors added more towers and ramparts. Charles I of Anjou reinforced the walls at the end of the 13th century, Ferdinand I King of Naples strengthened them two centuries later and 18th century rulers added still more. During the 19th century the castle served as a prison, and since the 19th century it has been an Italian Navy base, and is strictly closed to the public aside from organised tours.
