Gallia Lugdunensis (
French:
Gaule Lyonnaise) was a
province of the
Roman Empire in what is now the modern country of
France, part of the Celtic territory of
Gaul formerly known as
Celtica. It is named after its capital
Lugdunum (today's
Lyon), possibly Roman Europe's major city west of Italy, and a major imperial mint. Outside Lugdunum was the Condate Altar, where representatives of the Three Gauls met to celebrate the cult of
Rome and Augustus.
