Overview
Ephesus lies near the modern town of Selçuk in İzmir Province, where the Cayster (Küçük Menderes) plain meets hills that once held a fortified acropolis. Greeks founded the city in the early Iron Age; under Persian, Hellenistic, and Roman rule it grew into one of the largest urban centres in the Mediterranean, with a population that may have reached hundreds of thousands in the imperial period.
The Temple of Artemis, rebuilt on a marshy terrace, became one of the Seven Wonders of the ancient world. Today a single re-erected column marks the temple platform; most sculpture survives in museums. Roman Ephesus is what visitors walk: the Curetes Street, the façade of the Library of Celsus, the Great Theatre that held an estimated 25,000 spectators, and the terrace houses with frescoes and mosaic floors under protective roofs.

The harbour that made Ephesus rich silted progressively; by Byzantine times the sea had retreated kilometres west. Excavations by Austrian archaeologists since 1895 mapped the marble city; Turkish and international teams continue in the terrace houses and Artemision.

Homer's epics do not stage action at Ephesus, but the Ionian coast belongs to the same Greek-speaking world as Troy and the islands Odysseus wanders. In the Odyssey, Asia Minor appears in stories of storms, raiding, and hospitality; a later reader easily imagines Ephesian harbours in that network. Today Ephesus is a common shore excursion for travellers circling the Aegean after visiting Troy or the Greek mainland palaces.
Film crews love the Library of Celsus façade for its instant "ancient city" readability. The archaeology rewards slower pacing: start at dawn, read the inscriptions, and remember the city was a harbour long before it became a marble stage set.
