Apart from its rich ethnographic collection and its exhibition of known and less known Croatian artists in various media and styles, the central cultural institution of the Town of Novalja is famous for the so-called Talijanova buža, a 1.2 km long antique underground aqueduct with an entrance located in the museum and a visible first section of the aqueduct (the aqueduct itself is not open to visitors).
Numerous archaeological sites and remains, including the unique ancient Roman aqueduct from the 1st century, the only one of its kind on the Croatian Adriatic coast, attest to a thousand-year old history and the turbulent times Novalja went through. The Roman conquerors had a particular influence throughout the 1st century BC. Thus, the Roman culture left its mark for many centuries to come. There was a strong Christian community in Novalja back in the 4th and 5th century. That's where the three magnificent basilicas were erected. The early Christian Novalja was a well-known pilgrimage centre of the ancient world. Part of the numerous archaeological finds has been preserved at various sites and the other part of the findings can be found in the Stomorica archaeological collection located next to the Parish Church of St. Catherine.
