Frontiers of the Roman Empire – The Lower German Limes

This first postcard was one of the first postcards that I received through Postcrossing and I had no idea that was on the UNESCO list until I saw a postcard of Colonia Ulpia Traina (the same thing that says in my postcard) in the SL Liew's UNESCO Postcard blog. After confirmation of Marcel, another postcrosser who already sent me a few postcards and knows the site, voilá, new UNESCO in my collection! The others arrived to my mailbox after the inscription.

Xanten is a town in the state of North Rhine-Westphalia, Germany. 

Xanten is known for the Archaeological Park, one of the largest archaeological open air museums in the world, built at the site of the Roman settlements Colonia Ulpia Traiana.

The Archäologischer Park Xanten is built on the site of the Roman town, and it is one of the most frequently visited parks in Germany. In 2012, the Archaeological Park was expanded to nearly the whole area of the Roman colonia after Bundesstraße 57 was moved away from the area. - in: wikipedia

The Lower Germanic Limes (Latin: limes ad Germaniam inferiorem, Dutch: Neder-Germaanse Limes, German: Niedergermanischer Limes) is the former frontier between the Roman province of Germania inferior and Germania Magna. The Lower Germanic Limes separated that part of the Rhineland left of the Rhine as well as the Netherlands, which was part of the Roman Empire, from the less tightly controlled regions east of the Rhine.

The Lower Germanic Limes was not a fortified limes with ramparts, ditches, palisades or walls and watchtowers, but a river border (Lat.: ripa), similarly to the limites on the Danube and Euphrates. The Rhine Line was guarded by a chain of castra for auxiliary troops. It was laid out partly by Augustus and his stepson and military commander, Drusus, who began to strengthen the natural boundary of the Rhine from the year 15 A. D. The decision not to conquer the regions east of the Rhine in 16 A. D. made the Rhine into a fixed frontier of the Roman Empire. For its protection, many estates (villae rusticae) and settlements (vici) were established. - in: wikipedia

Traiectum was a Roman fort, on the frontier of the Roman Empire in Germania Inferior. The remains of the fort are in the center of Utrecht, Netherlands, which takes its name from the fort.

In the Roman Empire Traiectum was one of the forts in the lower Limes Germanicus defensive lines. The Emperor Claudius defined the Rhine downstream from Bonn as the western part of the frontier. He ordered the legions further north to withdraw to this line, which was fortified in AD 47. The Rhine divides into several branches in the Netherlands. The army chose the branch on which modern Utrecht lies as the frontier. - in: wikipedia
