The Allobroges were a Gallic people dwelling in a large territory between the Rhône river and the Alps during the Iron Age and the Roman period.

The Rhône is a major river in France and Switzerland, rising in the Alps and flowing west and south through Lake Geneva and southeastern France before discharging into the Mediterranean Sea. At Arles, near its mouth, the river divides into the Great Rhône and the Little Rhône. The resulting delta forms the Camargue region.
