Following the left bank of the Lower Rhine River for approximately 400 km from the Rhenish Massif in Germany to the North Sea coast in the Netherlands, the transnational property consist of 102 components from one section of the frontiers of the Roman Empire, which in the 2nd century CE, stretched across Europe, the Near East, and North Africa, over 7,500 km. The property comprises military and civilian sites and infrastructure that marked the edge of Lower Germany from the 1st to 5th centuries CE. Archaeological remains in the property include legionary fortresses, forts, fortlets, towers, temporary camps, roads, harbours, a fleet base, a canal and an aqueduct, as well as civilian settlements, towns, cemeteries, sanctuaries, an amphitheatre, and a palace. Almost all of these archaeological remains are buried underground. Waterlogged deposits in the property have enabled a high degree of preservation of both structural and organic materials from the Roman periods of occupation and use.
