The historical town of Giovinazzo, called Natiolum during the Roman Empire, is nowadays a charming seaside town closed to Bari; it has been mentioned throughout centuries by its most eminent fellow citizens such as William of Apulia (a chronicler of the Normans) and the medieval writer Matteo Spinelli. Once Benedictine nuns’abbey (XI Cent.), the St. Martin Hotel, is today a precious chest where treasures like the ancient gate of the town (VII-III Cent. B.C.) and remains of the early Christian Episcopal church (III Cent. A.D.) are locked for.
