ALPES GRAIAE ET POENINAE Or, Alpes Poeninae et Graiae.
Roman province. In the early 3rd century, simply Alpes Graiae. The Graian Alps are separated from the Mont Blanc massif by the Little St Bernard Pass; the Pennine Alps, further north, have the Great St Bernard between them and Mont Blanc.
In Augustus’s day, it had been the most northerly of the three Alpine provinces between Gaul and Cisalpine Gaul (present-day northern Italy). In the reorganisation of the late 3rd century the province belonged to the diocese of Gallia.
