Ancient Elyros, situated on Crete's 'Kefala' hill near Rodovani, originated in the Early Iron Age and thrived until Late Antiquity. Named after the mythical son of Apollo, it became a major urban center in southwestern Crete during the Classical period, known for trade and weapon manufacturing. As a leading city in the Oreioi League (formed in the 3rd century BC for security and economic reasons, including Hyrtakina, Lissos, Poikilasio, Syia, and Tarra), Elyros maintained external connections before the league's likely dissolution before 183 BC, a period when it was at war with Kydonia. The Roman era marked a time of flourishing for Elyros, evidenced by the "Philosopher of Elyros" statue. The city featured fortification walls, an aqueduct, cisterns, and a theater. Elyros minted its own coins, indicating autonomy, with emblems similar to Hyrtakina's. Its territory included the port of Lissos, a key economic contributor and religious center with an Asklepieion, as well as the coastal cities of Syia and Poikilasio. Archaeological findings suggest communication with mainland Greece, North Africa, and Southern Italy. Notably, Elyros had a local workshop producing unique glass pyxides. A rural sanctuary dedicated to Poseidon was also found in the 'Tsiskiana' area, likely under Elyros's jurisdiction.
