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.
