Just north of Punta Libeccio, at about 100 m from the coast, a site known as the “Relitto dei Cannoni” (the “Wreckage of Cannons’’) can be found at a depth of 15 m. The gently sloping seabed, which is characterised by naturally split rocks alternating with clearings of sand and gravel, contains traces of an ancient shipwreck: eight cannons of uniform size and characteristics, six of which are lying in disarray along a vaguely rectilinear axis, while the other two are offset by about 20 m to the west. The total distance between the farthest cannons is about 30 m. 

The itinerary is marked by a guiding rope, which is initially fastened to the wall, and then to the bottom at a depth of 29 metres. The dive starts (with sign 0) at the mooring buoy, following an S/N heading. After a brief pause on the top of the shoal, you will begin your descent and will encounter the first artefacts at a depth of about 30 m. Keeping the wall of the shoal on the left and turning right (at sign 2), you will come to the observation platform at a depth of about 30 m (sign 3), from which you can observe wreck A, known as “Roghi” (from the 2nd century B.C.), which is located at depths ranging from 36 to 45 metres. Re-ascending to the depth of 28 m, you will come to a cave (sign 4) that boasts an abundance of natural features. Continuing on, a stone anchor dating back to the fifth century B.C. can be found in the vicinity of a landslide, at a depth of around 25 m (sign 5). Heading back towards the surface, the route turns south through a channel full of small caves (sign 6) at around 8 m, where remains of more recent origins can be found. From here, you will soon return to the starting point (sign 0).
