Castello Svevo, Hohenstaufen castle in Augusta, Italy
Castello Svevo is a medieval fortress on an island off the coast of Augusta with a square layout and four corner towers. A pentagonal bastion beside the southern entrance further strengthens the defensive structure.
Emperor Frederick II commissioned the fortress in 1232 and appointed Riccardo da Lentini to design this military stronghold. The structure emerged as part of his strategy to control southern Italian territory.
The fortress blends Roman military architecture with medieval defense principles developed during Frederick II's reign. Visitors can observe this mix of styles in the walls and towers that define the building today.
The fort sits on an island connected to the mainland by a bridge and is easy to reach. Part of the complex is now used by a police station, so not all areas are open to visitors.
From 1890 to 1979 the medieval fortress served as a prison and underwent extensive modifications. This use as a jail left clear marks on the interior layout that remain visible today.
