Polignano a Mare (Italian: [poliɲˈɲaːno a mˈmaːre]; Barese: Peghegnéne [pəɡəɲˈɲeːnə]) is a town and comune in the Metropolitan City of Bari, Apulia, southern Italy, located on the Adriatic Sea.

Nowadays, some historians suggest that this latter was one of the two colonies founded during the 4th century BC by Dionysius II of Syracuse; other sources, instead, claim Julius Caesar as the father of Polignano a Mare, which might have been a central hub along the well-known Via Traiana.

Thanks to its strategic position on the Adriatic Sea, it soon became a trade centre, at least until the introduction of a Greek coin bearing the "NEAII" inscription.

[4] The fortification of the suburb, on the other hand, has plainly to be attributed to the Angioinians, who secured the protection of the land from potential threats including the Turkish army and the different kinds of epidemics.

[5] Under the Aragonese crown, Polignano reached its peak in both economic and cultural terms; this meant business men and merchants coming from different parts of the world meeting there soon afterwards.
