The island of Pag, and especially the western part of the island of Pag, the area of Novalje was populated in the pre-antic period by Illyrian tribes of Liburns, who resided in fortresses whose remains can be detected even today and topographically reconstructed.

With the arrival of Roman conquerors in the first century Before Christ, a Roman government was established with the headquarters in Cissa, which, according to the legend, was destroyed by an earthquake in the 3rd century. Today it is the area of Caska, the favorite Novalja beach where systematic archeological research is taking place. From that time there are three basilicas where the urban one guards the remands of the floor mosaic with an apsidal of thirteen meters. The most important archeological and cultural artifact was found on the site of the urban basilica – the reliqiary from the IV century who is kept in the archeological museum in the city of Zadar.

Along with the basilica, the most attractive historical monument is part of the Roman aqueduct carved into a live rock, 1,2 kilometers long which touched the waters in Novalja, an antic harbor. That unique aqueduct can be seen the in the city museum.

The collected archeological building is guarded in the archeological Stomorica collection and is available to interested visitors.
