The sea of ​​Ustica often has stories to tell and some already belong to the past. Once inside the San Paolo Point Cove, at a depth of 14 meters, there was an Islamic or Byzantine iron anchor dating back to the eighth or ninth century. A.D .. It was not always visible even to the most experienced divers: the posidonia often enveloped it, hiding it, as if it were jealous. It is thought that it belonged to a boat that found itself having to quickly leave its mooring, abandoning the anchor on the bottom. This is of a type almost never found in Sicily, which is why some scholars speculate that it may have belonged to pirates interested in conquering the island. San Paolo Point is located in zone C of the Ustica Island ProtectedMarine Area.
