An isolated area approximately 1 km from shore where the rocks just break the surface.  Consequently, an area of many shipwrecks in ancient times which is now littered with pieces of amphorae.  In some areas, these pieces are cemented together in the shape of a ship’s hold.  Stone anchors can be recognised by the holes made in the rock for wooden grapples to be pushed through.  Depths 4m -12 m.
