The empire around 400 CE. The broad colours represent prefectural groupings, while regional names, major cities, and symbols for selected state industries show the larger administrative and logistical setting. These groupings contained many individual provinces; a region labelled on this map is not necessarily one province.

The province emphasized Alpine valleys and approaches rather than the whole older upper Danubian frontier. Farming in suitable districts, livestock, transport, and mountain routes connected its communities to Italy and the northern forelands. Its civil government belonged to the Italian grouping, while military responsibilities could be coordinated with neighbouring Raetia Secunda.

In late antiquity, local power, church organization, and surviving settlement preserved regional connections despite weakening imperial support. Different valleys experienced political change differently. The province’s later inheritance therefore cannot be reduced to the fate of one Danubian legionary base or to a modern national border across the Alps.
