Die (French: [di] ⓘ; Vivaro-Alpine: Diá [djɔ]; Arpitan: Dia [dja]) is a commune, a former episcopal see, and a subprefecture of the Drôme department in southeastern France.

[5] Die is situated in the valley of the river Drôme, surrounded by the Glandasse mountain (6,696 feet; 2,041 m), a massive and steep rocky barrier, which separates the area (Pays Diois) from the Vercors Plateau.

A large engraved standing stone and two small menhirs that are now in the Die museum were found near the wine cooperative further proving habitation in this area at that time.

There is much evidence of the extensive urbanisation during the 1st century.At the beginning of the 2nd century, the town of Die saw the construction of monumental architecture and also replaced Luc-en-Diois as the Roman provincial capital for the Celtic people of northern Voconces.

It achieved the formal status of a colony towards the end of the 2nd century or during the 3rd century as shown by the town becoming an important centre of worship for the fertility goddess Cybele’s When the Roman Empire was showing signs of weakness, between the 285 and 305, a fortified wall was constructed around the town, protecting an urban area of 25 hectares (62 acres), this wall is just over a mile long.

By contrast, Die now receives a significant number of tourists during summer, from countries such as The Netherlands and Belgium who use the many camp sites around the Drôme valley.
