Vindobona

Modern Vienna, city on the Danube River, to the west of Carnumtum, in the province of Pannonia Superior. Originally a Celtic community, the site was seen as ideal for Roman occupation, and by the end of the first century C.E. , its status had been increased to municipium; it was headquarters of the X Gemina Legion and the main port of the Classis Pannonica, an imperial river fleet. While it did not possess the political power of the provincial capital, Vindobona was clearly important in a strategic sense.
