In the center of the great Calatubo valley, stands a solitary fortress about one hundred and fifty meters high, on top of which the Castle sits. The fortress appears inaccessible to those coming from the sea, although, in reality, it can be reached from the south-west side which has a sloping surface.
The fortress, due to its position, has always been a strategic point in which to retreat to protect oneself against possible attackers. In ancient times, it was a garrisoned site during the period of Greek colonization in Sicily and then a military outpost in the Roman, Byzantine and Norman periods, making it a fortified and strategic outpost for territorial and road control.
With the Arab domination, the castle no longer had a military function and was used as a residence and farm, to support the vast fiefdom, by the various nobles who followed one another as owners.
