Tres Alpes

The Roman empire in the time of Hadrian (ruled 117–38 AD), showing, in the western Alps mountain range, the Tres Alpes, the provinces of Alpes Graiae (1), Alpes Cottiae (2) and Alpes Maritimae (3)

Tres Alpes (literally, "Three Alps"), was the collective term used by the Romans to denote three small provinces of the Roman empire situated in the western Alps mountain range, namely Alpes Graiae (or Poeninae) (Val d'Aosta, Italy); Alpes Cottiae (Val di Susa, Italy); and Alpes Maritimae. The region was annexed by the Romans in 16–14 BC and the three provinces organised by 7 BC.[1]
