In Roman times it was a resort as evidenced by the discovery of a villa under the church of Santa Maria Assunta. Access to the villa took place by sea. From the tenth to the twelfth century was part of the Duchy of Amalfi.
The Middle Ages saw the construction of several towers for the sighting of the Saracens, the authors of numerous incursions and raids against the local population. The first tower is located outside the town of Positano, at Punta Campanella, where it ends and begins the Amalfi Coast and Sorrento Peninsula. From there, spotted the Arabs, they threw the first signal, a cannon shot, and this then the tam tam moved to the second, third and so on, along Positano and the Amalfi Coast. In this way, Positano could take refuge on the steep hills (so we have created the villages of Montepertuso Nocelle). In fact, the Saracens, skilled sailors and soldiers, were disadvantaged nell'addentrarsi on the hills, and they were easy prey for counterattacks by the local population.
