Following the Roman conquest of Provence, Barcelonnette was included in a small province with modern Embrun as its capital and governed by Albanus Bassalus. This was integrated soon afterwards into Gallia Narbonensis. In 36 AD, Emperor Nero transferred Barcelonnette to the province of the Cottian Alps. The town was known as Rigomagensium under the Roman Empire and was the capital of a civitas (a provincial subdivision), though no Roman money has yet been found in the canton of Barcelonnette.
