Danube may be one factor, missing political interest in the town after the time of Justinian may be another. Among many other imported finds the presence of 2 pieces of a specific type of fibulae and handmade pottery have been understood as an indication of the presence of Slavs already before the Avar incursion. Archaeological site The huge correlation between the archaeological site and the description by Procopius as well as finds of seals of the bishop of Iustiniana Prima have determined the identification of Justiniana Prima with Caričin Grad. There have been archaeological excavations for nearly 100 years with the participation of French and more recently also German researchers. There is a permanent exhibition in the national museum in Leskovac. At the site itself monuments there are impressive remains of the fortification, the acropolis as well as of several churches and many other buildings.
