Before the [[Ancient Rome|Roman]] conquests of [[Gaul]], the territory of Arlon and a vast area to the southeast were settled by the [[Treveri]], a [[Celts|Celtic]] tribe.  The local population adapted relatively easily to Roman culture.  The number and quality of sculpted stones and monuments that have been unearthed in the area demonstrate that the [[Vicus (Rome)|''vicus'']] of ''Orolaunum'' quickly became a commercial and administrative centre of Roman civilization.  The Germanic invasions of the 3rd century destroyed most of these early advances, despite the defensive walls that had been built on the Knipchen hill to protect the ''vicus''.
