We are in front of the Torre Truglia. This was a watchtower and was built on the remains of an ancient Roman tower. Its construction dates back to 1532. Only 2 years later it was destroyed by Saracen raids led by Kair Ed Din known as Barbarossa.
It was later rebuilt in 1611 and was later destroyed in 1623 by the Turks. In the following years it was used as the headquarters of the Guardia di Finanza.
