The Roman military camp and the capital of the Roman province of Upper Moesia has been the subject of archaeological research over the past four decades.
The destruction of Viminacium under the advance of the Huns may be compared to the famous destruction of Pompeii and Herculaneum under the eruption of Vesuvius. Accommodating some fifty thousand inhabitants,
Viminacium was an important economic, military and strategic centre in Roman times. The archaeological park was open to tourists on October 2006. Visitors are mostly attracted by the Royal Roman Mausoleum and the collection of frescoes containing late antique masterpieces. The site is located ninety kilometres south of Belgrade, close to Kostolac.
