It is an ancient city in the central Aegean region of Turkey that was founded about 3,000 years ago by Ionian immigrants, near contemporary Selçuk. Its excavated remains reflect centuries of history, from classical Greece to the Roman Empire, when it was the main commercial center of the Mediterranean until the spread of Christianity. The archaeological site of Ephesus is one of the most impressive in the ancient world in the Mediterranean. After many decades of archaeological and restoration work, Ephesus appears as the most complete Greco-Roman city and only 20% of what is estimated to have been this great metropolis in its heyday has been unearthed. As the capital of Roman Asia Minor, it was a great city of 200,000 inhabitants, and its port and great temple of Artemis attracted an incessant flow of merchants and pilgrims. It was declared a World Heritage Site by UNESCO in 2015. Currently excavations and reconstructions continue, so it is very likely that in a few years it will be an even more impressive place. On a visit to Ephesus, these would be the archaeological remains that you should not miss: Baths of Ephesus, State Agora, Odeon, Pritaneo, Sacred Quarter, Sacred Ramp, Temple of Ephesus, Nike Relief, Hidreion Fountain, Gate of Heracles, Nymphaeus of Trajan, Baths of Varius, Temple of Hadrian, hillside houses, Hadrian's Gate, Celsus Library, South Gate, Ephesus Trade Agora, Via Arcadiana, the Great Theater and the Temple of Artemis.
