Ephesus was one of the great cities of the Ionian Greeks in Asia Minor, located in Lydia where the Cayster river flows into the Aegean Sea (in modern day Turkey). It was founded by colonists principally from Athens. The ruins of Ephesus are a major tourist attraction, especially for people travelling to Turkey by cruise ship via the port of Kusadasi. The many-breasted "Lady of Ephesus", identified by Greeks with Artemis, was venerated in the Temple of Artemis, the largest building of the ancient world, according to Pausanias (4.31.8) and one of the Seven Wonders of the World, of which scarcely a trace remains.
