The Lower Germanic Limes extended from the Vinxtbach near Bad Breisig to the mouth of the Rhine in the North Sea. Thus, it has a total length of approximately 400 km. Since 2021, this section of the Limes with 44 sub-sites has been part of the transnational World Heritage Cluster "Frontiers of the Roman Empire". The German section of the Lower Germanic Limes ends at the German-Dutch border near Kleve. The sites of the Lower Germanic army (exercitus Germaniae inferioris) were lined up like a string of pearls along the ancient riverbank. The Rhine served as the main stationing area for the legions with the most important legion camps in Nijmegen, Xanten, Neuss and Bonn. Cologne-Marienburg was also the central base of the Rhine fleet (classis Germanica), which operated as far as the North Sea.
