Transalpine Gaul

Extracted from the Wikipedia article Gallia Narbonensis.
Founding
The province had come into Roman control originally under the name Gallia Transalpina (Transalpine Gaul), which distinguished it from Cisalpine Gaul on the near side of the Alps to Rome. In this strip of land, the Romans founded the town of Narbonne in 118 BC. At the same time, they built the Via Domitia, the first Roman road in Gaul, connecting Gaul to Hispania, and the Via Aquitania, which led toward the Atlantic through Tolosa (Toulouse) and Burdigala (Bordeaux). Thus, the Romans built a crossroads that made Narbonne an optimal trading center, and it became a major trading competitor to Massilia. From Narbonne, the Romans established the province of Transalpine Gaul, later called Gallia Narbonensis.
