Giovinazzo is a town and former bishopric within the Metropolitan City of Bari, Apulia region, southeastern Italy. It was a small fortified centre of the Romans, who called it Natolium, maybe built on the ruins of the Peucete Netium which was destroyed during the Punic Wars. The main sights are: the Co-cathedral, dedicated to Santa Maria Assunta (Mary’s Assumption), built in the Norman period 1150–1180, in characteristic Apulian Romanesque style featuring Eastern and Western elements and the Ducal Palace. In the neighbourhood is Castel del Monte, one of the most famous castles in southern Italy.
