Ephesus (Greek: , ), was one of the great cities of the Ionian Greeks in Asia Minor, located in Lydia where the Cayster River (Küçük Menderes) flows into the Aegean Sea (in modern day Turkey). It was founded by colonists principally from Athens. The ruins of Ephesus are favourite domestic and international tourism attractions, due to easy accessibility via İzmir ADB airport and via the port of Kuşadası.
