 The improbability of the identification with Krastos and the controversial localization of Demenna, does not exclude that the actual habitation was born by the progressive abandonment of the settlement located more towards the mountain which is a common phenomenon in Apennine regions.To this conclusion could be brought for example the remains of human settlement present until a few years, even at Crasto.The settlement probably took the Arab name of "Akaret" (meaning fortress) during the Islamic domination in Sicily.
