Potentia (ancient city)
Porto Recanati, Italy
Potentia was a Roman town along the central Adriatic Italian coast, near the modern town of Porto Recanati, in the province of Macerata. Its original position was just north of the main Roman bed of the River Potenza (the ancient Flosis), which now flows more than 1 km (0.62 mi) to the north.
