Trier (Luxembourgish: Tréier; Italian: Treviri, French: Trèves) in Rheinland-Pfalz, Southwestern Germany lies on the river Mosel in a valley between vine-covered hills, near the border with Luxembourg in an important wine-growing region. Founded by the Romans in the 1st century BC as Augusta Treverorum, it may be the oldest city in Germany. It’s also the oldest seat of a bishop north of the Alps. In the Middle Ages, the Archbishop of Trier was important as he controlled land from the French border to the Rhein. He also had great significance as 1 of the 7 electors of the Holy Roman Empire. With a population of 105,000, Trier is now the 4th-largest city in its state after Mainz, Ludwigshafen, and Koblenz. The nearest major cities are Luxembourg (50 km), Saarbrücken (80 km), and Koblenz (100 km). Trier is home to the University of Trier, founded in 1473, closed in 1796 and restarted in 1970. The city also has the Trier University of Applied Sciences. Apart from the local wines and beers (local Löwenbräu, or Gaffel Kölsch & Bitburger), one should definitely try Viez or Viez/Limo. It’s an apple wine, often served with a splash of lemonade.
