At this point, sailors used to moor their vessels when the weather did not allow them to continue their journey. During such moments they prayed to the gods either to thank them for being rescued from the bad weather, or to plead to them to safely continue their travels.
They used to smoothly carve their prayers on the cliffs of the coast while waiting for the right weather conditions that would allow them to take off once again. For this reason the cove was named “Grammata” meaning letters.
According to archaeologists the inscriptions date back all the way from the classical antiquity and up to the middle ages.
