The Roman Limes in the Netherlands: how a delta landscape determined the location of the military structures

A new palaeogeographical reconstruction reveals that the distinctive landscape of the Lower Rhine delta, characterized by numerous tributaries, dictated the spatial arrangement of Roman military structures. All forts (castella) were strategically placed on southern natural levees along the river Rhine, regardless of subsoil conditions, to guard waterways and control access from Germanic territories and the Meuse tributary. This integrated system of castella and watchtowers initially served as a defensive barrier against Germanic invasions and facilitated secure transport routes for army supplies during the British invasion in 43 A.D., later evolving into a frontier zone by the end of the first century. The study leverages LIDAR-derived digital elevation models, soil maps, and excavation data to elucidate these environmental-military interactions.
