The name (in local pronunciation Arcaton) comes from the Greek and Byzantine occupation dated back to the sixth century AD: "Archeion" is the name of a plant, the burr, which still grows spontaneously in some areas of the beach now occupied by the bathing establishments but which was once abundant on the desert shore of Riccione.
