View looking east. The green field in the foreground is part of the silted harbor of Seleucia Pieria. The ashlar stone walls are part of the retaining walls of the agora, which was situated beyond them. Part of the city, including an Ionic Temple was situated on the hill in the upper center portion of the image.
Seleucia Pieria was a major port that connected Syria with Rome. The capital of Syria was first here but then moved to Antioch on the Orontes—a huge city. This port, 18 miles west of Antioch, then served as its port.
The Apostle Paul, Barnabas, and John Mark set sail from here at the beginning of Paul's First Missionary Journey (Acts 13:4)
