The town lies in the north of the Abruzzo region, between the Salinello and the Tordino rivers.

Giulianova is split between the Paese, the historic town up in the hills, and the Lido, the more recent development down by the beach

Tourism plays a big part in the town's economy. The town, characterized by several beaches, is a summer retreat for people from large cities like Rome and Milan, as well as German and French tourists.

In pre-Roman times, the Praetutii tribe had a settlement called Castrum Novum in the vicinity of Giulianova. In the Middle Ages, the population of Castrum Novum, then called Castrum divi Flaviani, were moved to the new hilltown of Giulia, founded by the local baron Giulio Antonio Acquaviva.

Under the arch are 18 stone tiles depicting enigmatic figures, described by some a representation of the Zodiac and the seasons. The octagonal Cathedral of San Flaviano, was built in 1472
