Viminacium was a major city of the Roman province of Moesia (today's Serbia), and the capital of Moesia Superior. Viminacium was the base camp of Legio VII Claudia, and hosted for some time the IIII Flavia Felix. It was destroyed in 440 by the Huns, but rebuilt by Justinian I. During Maurice’s Balkan campaigns, Viminacium saw destruction by the Avars in 584 and a crushing defeat of Avar forces on the northern Danube bank in 599, destroying Avar reputation for invincibility.
Today Kostolac, a small Serbian town on the Danube river, is located where Viminacium used to be.
In August 2009 I paid a visit to this special site together with Dick Mol to make the pictures you can see at this page.
