PROSPEROUS PERGA. During his two visits to the city, Paul would have walked along the city’s main street, the Cardo Maximus. A freshwater channel ran through the center of the thousand-foot-long colonnaded promenade that was lined with covered walkways and shops in structures such as the one shown here. Over six decades of excavations at Perga have exposed extensive remains from the Roman city, which continued to prosper for centuries after Paul and Barnabas’s visit. But no synagogue has been found, despite evidence of a Jewish population there.
