- Castello Aragonese (Aragonese Castle): Built on a rock near the island in 474 BC, by Hiero I of Syracuse. In 1441 Alfonso V of Aragon connected the rock to the island with a stone bridge instead of the prior wood bridge, and fortified the walls in order to defend the inhabitants against the raids of pirates. Around 1700, about 2000 families lived on the islet, including a Larisses Convent, the Abbey of Basilians from Greece, the Bishop and the Seminar, the Prince with a military garrison. There were also thirteen churches.
