Vindobona

Vindobona (Celtic/Gaulish windo- "fair/white/blessed", bona "base/bottom", presumably so-named from its geological/topological position) was originally a Celtic settlement, and later a Roman military camp on the site of the modern city of Vienna in Austria. Around 15 BC, the kingdom of Noricum was included in the Roman Empire. Henceforth, the Danube marked the border of the empire, and the Romans built fortifications and settlements on the banks of the Danube, including Vindobona.
