Upper Germanic-Rhaetian Limes

The Upper Germanic-Rhaetian Limes (Obergermanisch-Raetischer Limes), or ORL, is a 550-kilometre-long section of the former external frontier of the Roman Empire between the rivers Rhine and Danube. It runs from Rheinbrohl to Eining on the Danube. The Upper Germanic-Rhaetian Limes is an archaeological site and, since 2005, a UNESCO World Heritage Site. Together with the Lower Germanic Limes it forms part of the Limes Germanicus.

The Limes used either a natural boundary such as a river or typically an earth bank and ditch with a wooden palisade and watchtowers at intervals. A system of linked forts was built behind the Limes.

Terminology


The term limes (plural: limites) originally meant "border path" or "swathe" in Latin. In Germany, "Limes" usually refers to the Rhaetian Limes and Upper Germanic Limes, collectively referred to as the Limes Germanicus. Both sections of limes are named after the adjacent Roman provinces of Raetia (Rhaetia) and Germania Superior (Upper Germania).

In the Roman limites we have, for the first time in European history, clearly defined territorial borders of a sovereign state that were visible on the ground to friend and foe alike. Most of the Upper German-Rhaetian Limes did not follow rivers or mountain ranges, which would have formed natural boundaries for the Roman Empire. It includes the longest land border in the European section of the limes, interrupted for only a few kilometres, by a section that follows the River Main between Großkrotzenburg and Miltenberg. By contrast, elsewhere in Europe, the limes is largely defined by the rivers Rhine (Lower Germanic Limes) and Danube (Danube Limes).

Function
The function of the Roman military frontiers has been increasingly discussed for some time. The latest research tends to view at least the Upper Germanic-Rhaetian Limes not as a primarily military demarcation line, but rather a monitored economic boundary for the non-Roman lands. The limes, it is argued, was not really suitable for fending off systematic external attacks. Thanks to a skillful economic policy, the Roman Empire extended its influence far to the northeast, beyond the frontier. Evidence of this are the many border crossings which, although guarded by Roman soldiers, would have enabled a brisk trade, and the numerous Roman finds in "Free Germania" (as far as Jutland and Scandinavia). Attempts were occasionally also made, to settle Roman legions beyond the limes or, more often, to recruit auxiliaries. As a result, the Romanization of the population extended beyond the limes.

Research history
Interest in the limes as the remains of a site dating to the Roman period was rekindled in Germany at the time of the Renaissance and Renaissance humanism. This was bolstered by the rediscovery of the Germania and  Annales of Tacitus in monastic libraries in the 15th and early 16th centuries.

Scholars like Simon Studion (1543-1605) researched inscriptions and discovered forts. Studion led archaeological excavations of the Roman camp of Benningen am Neckar on the Neckar section of the Neckar-Odenwald Limes. Local limes commissions were established but were confined to small areas, for example, in the Grand Duchy of Hesse or Grand Duchy of Baden, due to the political situation. Johann Alexander Döderlein was the first person to record the course of the limes in the Eichstätt region. In 1723, he was the first to interpret the meaning of the limes correctly  and published the first scholarly treatise about it in 1731.

Imperial Limes Commission
Only after the foundation of the German Empire could archaeologists begin to study more precisely the route of the limes, about which there had previously only been a rudimentary knowledge. As a result, they were able to make the first systematic excavations in the second half of the 19th century. In 1892, the Imperial Limes Commission (RLK) was established for this purpose in Berlin, under the direction of the ancient historian, Theodor Mommsen. The work of this commission is considered pioneering for reworking of Roman provincial history. Especially productive were the first ten years of research, which worked out the course of the Upper Germanic-Rhaetian Limes and named the camps along the border. The research reports on the excavations were published from 1894 to the dissolution of the Commission in 1937. The individual reports went under the title of The Upper Rhaetian Limes of the Roman Empire (ORL), which was published in fifteen volumes, of which seven cover the route of the limes and eight cover the various camps and forts. The documents of the Imperial Limes Commission are now in the custody of the Roman-Germanic Commission of the German Archaeological Institute. The RLK numbered the sections of the route, the forts and the watchtowers (Wp) on the individual sections.

Sections
In the course of this work the 550-kilometre-long route of the limes was surveyed, divided into sections and described. This division followed the administrative boundaries in 19th-century Germany and not that of ancient Rome:


 * Section 1: Rheinbrohl – Bad Ems
 * Section 2: Bad Ems – Adolfseck near Bad Schwalbach
 * Section 3: Adolfseck near Bad Schwalbach – Taunus – Köpperner Tal
 * Section 4: Köpperner Tal – Wetterau – Marköbel
 * Section 5: Marköbel – Großkrotzenburg am Main
 * Section 6: Stockstadt – Stockstadt am Main
 * Section 6a: Hainstadt – Wörth am Main (older Main Line)
 * Section 6b: Trennfurt – Miltenberg
 * Section 7: Miltenberg – Walldürn – Buchen-Hettingen (Rehberg)
 * Section 8: Buchen-Hettingen (Rehberg) – Osterburken – Jagsthausen (more recent Odenwald Line)
 * Section 9: Jagsthausen – Öhringen – Mainhardt – Welzheim – Alfdorf-Pfahlbronn (Haghof)
 * Section 10: Wörth am Main – Bad Wimpfen (older Odenwald Line/ Neckar-Odenwald Limes)
 * Section 11: Bad Wimpfen – Köngen (Neckar Line)
 * Section 12: Alfdorf-Pfahlbronn (Haghof) – Lorch – Rotenbachtal near Schwäbisch Gmünd (end of the Upper Germanic Limes, start of the Rhaetian Limes) – Aalen – Stödtlen
