Harbor Street was once the flamboyant promenade from the port into city center. The one-third mile walkway was flanked by a dramatic colonnade lined with shops. Beneath your feet was polished white marble. No doubt this was an impressive entry for first time visitors. You will be equally intrigued. But today, the name Harbor Street is a misnomer. The sea is now about six miles from the end of this road (also called Arcadian Street). The reason? The former port first filled with silt from the River Caystros before becoming a swamp and then land. This natural retreating of the harbor was one of the causes of Ephesus’ decline.
