Dating back to 1132 under the reign of Norman King Roger II, Castello Normanno-Svevo is a true architectural testament to history. Although it endured destruction in 1156 by King William I of Sicily, it was resurrected and fortified in 1233 under the patronage of the Holy Roman emperor Frederick II. Over time, it saw various transformations during the Angevin domination, and after being held by several noble families, it eventually became a prison and barracks under the King of Naples. Encircled by a moat on all sides, except its northern border with the sea, accessible via a bridge and gate to the south, the castle primarily features Aragon walls and the prominent Hohenstaufen tower. Today, it serves as a venue for exhibitions, preserving a rich tapestry of history within its walls.
