Philippi lies 9 miles inland from Kavalla. Its origin dates from about 360 BC but was reestablished by the Romans as a colony. Extensive ruins of temples, the forum, gates, reliefs of deities, a theater, a gymnasium, and other finds can be seen there. The photo is the traditional jail in which Paul and Silas sang praises until the an earthquake led to the conversion of their jailor. It originally was a cistern, but the location fits the location by being near the forum. Cisterns sometimes were used as jails.
