State Agora of Ephesus

The State Agora of Ephesus served as the political and administrative heart of the ancient city, one of the largest urban centers of the Roman world. Laid out in the Hellenistic period and substantially expanded under Augustus in the 1st century BCE, the rectangular plaza hosted civic assemblies, judicial proceedings, and official proclamations. Three sides were originally framed by two-story stoas — colonnaded porticoes — while the fourth was anchored by a temple commonly identified with the Isis cult, reflecting Ephesus's cosmopolitan religious life. Systematic excavations since the 19th century have uncovered the original paving, statue bases, and dedicatory inscriptions. Visitors today walk freely across the open-air site, which conveys the civic scale of a metropolis that once held more than 200,000 inhabitants.
