During the Gallo-Roman era which lasted until about 450, the Romans built and maintained a number of roads in the area including the "Kiem" (Latin "caminus", road) linking Trier to Reims through what is now Mamer. "Mambra" was a small Roman settlement on the banks of the Mamer river at the eastern end of today's Mamer. The Roman settlement was burnt by Germanic invaders around 276.
