Balkan campaigns, Viminacium saw destruction by the Avars in 582 and a crushing defeat of Avar forces on the northern Danube bank in 599, destroying Avar reputation for invincibility. Location and excavation Viminacium is located in Stari Kostolac (Old Kostolac) a Serbian town on the Danube river, east of Belgrade. Viminacium is the location of the first archaeological excavation in Serbia, which started in 1882, by Mihailo Valtrović, founder of archaeology in Serbia and the first professor of archeology at the college in Belgrade, but himself a non-professional archaeologist (he was an architect). The only help he received was from twelve prisoners for manual work, because the state did not have enough resources to provide him with a better work force. His research was continued by Miloje Vasić, the first Serbian trained archaeologist, in the mid 1890s. Serbian Queen Draga Obrenović visited the site and donated 100 gold ducats for further excavations, which is considered the first donation in Serbia given to the exploration of the Antiquity.

Many studies suggest that the military camp at Viminacium had a rectangular plan, measuring , and that is not far from its western wall of civilian settlement in an area of approximately . The Legionary camp in Viminacium is now in an area of arable land, so that Viminacium is easily accessible to researchers, but unfortunately also to robbers. The National Museum in Belgrade and Požarevac have 40,000 items found in Viminacium, of which over 700 are made of gold and silver. Among them are many objects that are rare and invaluable. The tombstones and sarcophagi are often decorated with relief representations of scenes from mythology or daily life. We have found numerous grave masonry construction. Especially interesting are the frescoes of the 4th-century tombs. The frescos of young women have high artistic value as examples of Roman art. During the excavation, an amphitheater was discovered, which with its 12,000 seats was one of the largest in the Balkans. One specific fresco of a young woman is labeled the jewel of Viminacium and the most beautiful fresco of the Late Antiquity. The fresco resembles somewhat a famous Mona Lisa and local archaeologists named it "Divina". The woman is dressed in a gold-hemmed dress, indicating high social status. "Divina" is the centerpiece
