Ephesus
Once the commercial center of the ancient world, Ephesus is an archaeological splendor and an essential stop on any visit to Turkey. The city, whose wealth and patronage support its splendid architectural program, was dedicated to the goddess Artemis. Her enormous temple, once considered one of the Seven Wonders of the Ancient World and rebuilt several times, dates back to the third century B.C. The city's ruins include a theater, a gymnasium, an agora, and baths, as well as the iconic Library of Celsus.
