Remains of Sirmium stand on the site of the modern-day Sremska Mitrovica, 55 km (34 mi) west of Belgrade (Roman Singidunum) and 145 km (90 mi) away from Kostolac (Roman Viminacium). Archaeologists have found traces of organized human life on the site of Sirmium dating from 5,000 BC.[5] The city was first mentioned in the 4th century BC and was originally inhabited by the Illyrians and Celts[6] (by the Pannonian-Illyrian Amantini[7] and the Celtic Scordisci[8]). The Roman emperors Trajan, Marcus Aurelius, and Claudius II prepared war expeditions in Sirmium. During work on the new Sremska Mitrovica trade centre in 1972, a worker accidentally broke into an old Roman pot, about 2m deep, over the site of an old Sirmium settlement. ./cache/en-wikipedia-org-76.html ./txt/en-wikipedia-org-76.txt
