On June 13th the traditional party with grilled fish, music, entertainment and fireworks, at Piazzale del Porto
History...
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.
