Ephesus

Ephesus delivers the most complete Greco-Roman city experience in the Mediterranean, anchored by the monumental Library of Celsus. Its restored façade and 25,000-seat theatre transport visitors back to the 2nd century AD with unmatched authenticity. The site receives over 2 million visitors annually, outperforming #3 Ani by a factor of 20 in yearly attendance. Streets paved in marble stretch for over a kilometer, lined with remnants of public baths and the Temple of Hadrian, whose reliefs remain 90% intact. Compared to Aspendos Theatre at #4, Ephesus offers broader historical scope and a density of structures that rivals any ancient city east of Rome.
