The name of Saint Sabina designates an area that was used as a small port already in the Roman age. It was a neighbourhood frequented by pilgrims, travellers and merchants, but also saw several pirates and Saracen raids, a circumstance that made it necessary to build a tower. However, it was destroyed after a short time and then rebuilt during a fortification campaign in the sixteenth century at half a mile from its first site. There is no ruin left of the first structure, while the more recent star-shaped construction is used as a private building. With a height of 11 metres, it clearly resembles a defence tower for protection from the use of fire-arms.
