Rising from the Aegean coastline near Kuşadası, the Ancient City of Ephesus is one of the best-preserved classical cities in the Mediterranean and a UNESCO World Heritage Site inscribed in 2015. Walking its marble streets feels like stepping into an open-air museum, with monumental facades still standing much as they did two thousand years ago.

From Legendary Founding to Roman Metropolis

Ephesus’s origins reach back to Greek legend, with ancient writers crediting its founding to the Ionian prince Androclus around the 10th century BC, on a site already associated with Amazon warriors in myth. Over the following centuries the city passed through Lydian, Persian, and Hellenistic control, was reshaped by Alexander the Great’s successor Lysimachus, and eventually became one of the great cities of the Roman Empire — for a time the capital of the Roman province of Asia and one of the largest urban centers in the ancient Mediterranean.

The city’s wealth and importance came largely from its harbor, which connected it to trade routes across the Aegean and beyond. Over the centuries, however, silt from the nearby Cayster River gradually filled in the harbor, pushing the coastline further away and slowly strangling the city’s role as a port. By the early Middle Ages, Ephesus had been largely abandoned in favor of the nearby hill town that would become Selçuk, leaving the ancient city remarkably intact beneath centuries of soil.

A City Uncovered

Systematic excavation began in the late 19th century and has continued for well over a century, led for much of that time by the Austrian Archaeological Institute. Only a fraction of the ancient city has been fully excavated, and archaeological work continues today, meaning the site still holds discoveries yet to come.

Highlights Along Curetes Street

The main visitor route follows Curetes Street, the ceremonial spine of the ancient city, past many of its best-known monuments:

• The Library of Celsus — the most photographed facade in Ephesus, built in the 2nd century AD as both a library and a monumental tomb for the Roman senator Celsus.
• The Great Theatre — carved into the hillside with a capacity for tens of thousands of spectators, once used for performances, gladiatorial contests, and public assemblies.
• The Terrace Houses — a covered complex of preserved Roman residences with surviving mosaics, frescoes, and marble floors, offering a rare look at how wealthy Ephesians actually lived.
• The Temple of Hadrian — a small but richly decorated temple with finely carved reliefs on its facade.
• The Fountain of Trajan and the Baths of Scholastica — reminders of the engineering and public amenities that defined Roman civic life.
• The Odeon and the Agora — respectively a small theater for concerts and civic meetings, and the bustling commercial heart of the city.

Ephesus in Early Christian History

Beyond its Greek and Roman heritage, Ephesus holds major significance in early Christian history. The Apostle Paul lived and preached in the city for roughly two years, and his New Testament Letter to the Ephesians is addressed to the community he helped establish there. The city later hosted the Third Ecumenical Council in 431 AD, and tradition connects it to the Basilica of St. John, built over the apostle’s traditional burial site on the hill above, as well as the legendary Cave of the Seven Sleepers nearby.

Guided Walking Tours

Because the site spans a large area with layers of history from different periods, guided walking tours are the most popular way to visit. Expert guides help bring the ruins to life, explaining how the city’s streets, markets, and public spaces functioned in daily Roman life, and pointing out details — inscriptions, carved graffiti, engineering features — that are easy to miss without background knowledge.

Visiting Tips

Ephesus has two main entrances — the upper (Magnesia) gate and the lower (Harbor) gate — and most guided visits walk downhill between them, which is easier than the reverse route. The site involves a fair amount of walking on uneven marble surfaces, so comfortable, sturdy footwear is essential, along with sun protection and water, especially in summer. Mornings tend to be cooler and less crowded. The site pairs naturally with visits to the nearby House of the Virgin Mary and the Temple of Artemis, and it’s a popular half-day (or longer) outing for guests based in Kuşadası for dental treatment who want to explore between appointments — though given the amount of walking involved, it’s worth pacing the visit around your treatment schedule and comfort level.
