Norman Swedish Castle
The date of construction is estimated at the turn of the eleventh and twelfth centuries. Several renovations have been recorded in the following centuries; those who have definitely made a significant imprint relate to 'extension of the fortress, to the' addition of a pentagonal tower and a wall, changes wanted by Constance D'Altavilla in 1198 and Emperor Frederick II in 1235.
Further additions and renovations were made in the following years, among them, those ordered by Charles V of Spain. The manor, part of the defensive plan general of the Viceroy of Naples (Don Pedro Toledo) for southern Italy, was transformed into a massive military complex with a triangular-shaped bastions. The castle today is the remain of four cylindrical towers, ramparts, walls with battered bases and a buttress with blind loggia.
