Polignano a Mare is an Italian town in the Apulia, located on the Adriatic Sea. The area was settled since prehistoric times, as shown by archaeological excavations in the locality of Santa Barbara.
It is believed that it is the site of the ancient Greek city of Neapolis of Apulia, attested by many coins. Remains of the Roman domination include the bridge on the Via Traiana.
The former cathedral includes works by the sculptor Stefano of Putignano.
