Die Befestigung auf dem Katzenberg bei Mayen und die spätrömischen Höhenbefestigungen in NordgallienMonographien des RGZM
On the Katzenberg near Mayen, a military fortification, one of the largest of its kind, existed from about 300 AD until the middle of the 5th century to protect the economic centre of Mayen.
Based on the results obtained there, 143 other hill fortifications in northern Gaul are examined. Oriented along traffic routes, especially waterways, these fortifications by no means have the character of hidden refuges. Rather, they can also be classified as military installations that were integrated into an overarching defence concept. They ensured the continuity of civil and economic life in rural areas. Thus, hilltop fortifications are one of the elements of a deep military defence in Late Antiquity.
