The Römerbrücke (Roman bridge) spanning the Mosel still has most of its original Roman-built stonework. Trier is a very walkable town, with most of its key sights located within easy walking distance in the old city center. But there is also a special tourist mini-train (called the Römer Express) that takes visitors on a 35-minute tour of Trier’s Altstadt
Trier is the oldest city in Germany. Situated on the Moselle (Mosel) River, not far from Luxembourg, the city is a treasure trove of Roman ruins. Known as the “Rome of the North,” Trier served as the key city of the Roman northern territories. We visited here when my brother was stationed at Spangdahlem AFB, Germany. Loved this town.
