Trier formerly and traditionally known in English as Trèves, is a city on the banks of the Moselle in Germany. It lies in a valley between low vine-covered hills of red sandstone in the west of the state of Rhineland-Palatinate, near the border with Luxembourg and within the important Moselle wine region.
Founded by the Romans in the late 1st century BC as Augusta Treverorum ("The City of Augustus among the Treveri"), Trier is considered Germany's oldest city.
