Near the tower, in a crack in the ground, you can go down to the Grotta di Minerva or delle Sirene, where it is said that Partenope found refuge here when she was far from the island of Li Galli. The reflection of the sea, together with the reflections of light that penetrate from its openings, amplify the mystical aura of the place. Climbing routes are traced on the external walls of the cave overlooking the sea. The descent to the cave is not suitable for everyone, spurs of rock, slippery in places, force you to hold on to ropes set up for sections of mountaineering difficulty. Along the rocky wall of descent it is said that a rock epigraph was carved in the Oscan language that mentions the names of those who worked on the landing in the 2nd century BC.
