After the Huns attack in the middle of 5^th century, the Eastern Roman Empire control on the Balkans was gradually consolidated. As the final phase of that process, since the 3rd decade of 6^th century, during the reign of emperor Iustinian (527 – 565), within the restructuring of the bordering areas of the Empire, a line of hillforts, settlements and refugia was (re)built in the Balkan hinterland. On our territory there were registered and investigated several sites – hillforts (Ćava in Lis, Sokolica in Ostra, Gradina in Vučkovica, Stojkovića gradina in Viča). The biggest and the most important hillfort, the administration center of the region was Gradina on the mountain of Jelica, founded of the high mountain position, far from the main roads. These hillfors, different by their character, do not last for a long time, the life was interrupted at the beggining of the 7^th century by final settling of Slavs.

Different aspects of short but dynamic life of the Early Byzantine hillforts are displayed in the Museum by findings from Gradina in Jelica. On the basis of the functional part of clothes and jewelry (buckles and fibulae) one can presume the way of dressing during this period, while the iron tools and pottery made of stone illustrate the economy and everyday activities of the inhabitants. Findings with the cross symbols (window frame made of stone found in Basilica A) or fragments of frescoes testify of Christian religion of the inhabitants of Gradina.
