“At the top of the great stone lighthouse, hidden beyond the ridge of the southern headland, the slaves were dousing the fires to greet the dawn. It was supposed to be a sacred place. According to Virgil, this was the spot where Misenus, the herald of the Trojans, slain by the sea god Triton, lay buried with his oars and trumpet.”
(Robert Harris, Pompeii, 2003.)
We assumed that the historic lighthouse, formerly on this raised section of the headland, has long since been replaced by a somewhat smaller version.
