Limes Pannonicus, the frontier of the Roman province Pannonia, along the Danube from Klosterneuburg Austria to Taurunum in Serbia.
To the north, it bordered those parts of the Roman province of Rhaetia that lay north of the Danube and guarded the eastern border of that part of Germania Superior that lay east of the Rhine.
In its final stages, the Upper Germanic-Rhaetian Limes was about 550 kilometres long and ran from Rheinbrohl, in the county of Neuwied in northern Rhineland-Palatinate, as far as Hienheim on the Danube.
They moved their bases back to the banks of the Rhine and Danube, which were much easier to defend militarily.
The monitoring of the Upper Rhine was the responsibility of the Classis Germanica; that of the Rhaetic Danube came under the Classis Pannonia, whose headquarters was in Aquincum/Budapest.
It ran along the Danube from Passau/Boiodurum to Zeiselmauer/Cannabiaca.
Every camp had its own river port or landing stage and a storage area because the Danube was not only border zone, but also the most important transport and trade route in the region.
The surveillance and security of the Danube and its tributaries were the responsibility of the Classis Pannonia.
Although this section of the frontier was relatively well protected by the Danube river border or Ripa, the Roman military presence here was always exceptionally strong (three military camps in Pannonia, but only one in Lower Pannonia) because especially after the abandonment of Roman Dacia in the late 3rd century, the pressure of migrant peoples from the east on this section of the limes intensified.
The tributaries emptying into the Danube offered cheap transport routes, but also made good approach routes for invaders and raiders.
In addition, at vulnerable points, units of the Danube fleet were stationed.
The Upper German-Raetian Limes covers a length of 550 km and runs between Rheinbrohlxc2xa0on the Rhine and Eining on the Danube, built in stages during the 2nd century.
