Upper Germanic-Rhaetian Limes
The Upper Germanic-Rhaetian Limes stretches 550 kilometres across the landscape between the rivers Rhine and Danube. It runs from Rheinbrohl to Eining on the Danube. Most of this border did not follow natural features like rivers or mountain ranges. Instead, Roman engineers built an earth bank and ditch with a wooden palisade running along the top. Watchtowers stood at regular intervals behind this defensive line. A system of linked forts was constructed further back from the main barrier. This structure created one of the longest land borders in European history during the Roman period. The only exception occurred for a few kilometres where the boundary followed the River Main between Großkrotzenburg and Miltenberg.
Modern research suggests the border served as a monitored economic boundary rather than a purely military defense line. The limes was not really suitable for fending off systematic external attacks. Thanks to skillful economic policy, the Roman Empire extended its influence far to the northeast beyond the frontier. Evidence of this trade includes many border crossings guarded by Roman soldiers that enabled brisk commerce. Numerous Roman finds have been discovered in Free Germania as far as Jutland and Scandinavia. Attempts were occasionally made to settle Roman legions beyond the limes or recruit auxiliaries. As a result, the Romanization of the population extended well beyond the physical wall itself.
Interest in the limes as remains of a site dating to the Roman period rekindled in Germany during the Renaissance. Scholars rediscovered the Germania and Annales of Tacitus in monastic libraries during the 15th and early 16th centuries. Simon Studion researched inscriptions and discovered forts between 1543 and 1605. He led archaeological excavations of the Roman camp at Benningen am Neckar on the Neckar section of the Neckar-Odenwald Limes. Local commissions were established but confined to small areas like the Grand Duchy of Hesse or Grand Duchy of Baden due to political situations. Johann Alexander Döderlein was the first person to record the course of the limes in the Eichstätt region. In 1723 he interpreted the meaning correctly and published the first scholarly treatise about it in 1731.
Only after the foundation of the German Empire could archaeologists begin to study more precisely the route of the limes. They made the first systematic excavations in the second half of the 19th century. The Imperial Limes Commission established itself in Berlin in 1892 under the direction of ancient historian Theodor Mommsen. This work is considered pioneering for reworking Roman provincial history. Especially productive were the first ten years of research which worked out the course of the Upper Germanic-Rhaetian Limes. Research reports on the excavations were published from 1894 until the dissolution of the Commission in 1937. The individual reports went under the title of The Upper Rhaetian Limes of the Roman Empire and appeared in fifteen volumes. Seven volumes cover the route while eight cover the various camps and forts.
The 550-kilometre-long route was surveyed, divided into sections and described during the commission's work. This division followed administrative boundaries in 19th-century Germany rather than those of ancient Rome. Section one ran from Rheinbrohl to Bad Ems. Section two extended from Bad Ems to Adolfseck near Bad Schwalbach. Section three covered Adolfseck through Taunus to Köpperner Tal. Section four stretched from Köpperner Tal across Wetterau to Marköbel. Section five connected Marköbel to Großkrotzenburg am Main. Section six began at Stockstadt and continued along Stockstadt am Main. A section sixa existed between Hainstadt and Wörth am Main as part of the older Main Line. Section sixb ran from Trennfurt to Miltenberg. Section seven extended from Miltenberg through Walldürn to Buchen-Hettingen on the Rehberg. Section eight moved from Buchen-Hettingen via Osterburken to Jagsthausen on the more recent Odenwald Line. Section nine went from Jagsthausen through Öhringen and Mainhardt to Welzheim and Alfdorf-Pfahlbronn. Section ten started at Wörth am Main and ended at Bad Wimpfen on the older Odenwald Line or Neckar-Odenwald Limes. Section eleven ran from Bad Wimpfen to Köngen along the Neckar Line. Section twelve extended from Alfdorf-Pfahlbronn through Lorch and Rotenbachtal near Schwäbisch Gmünd to Aalen and Stödtlen. Section thirteen covered Mönchsroth to Weiltingen-Ruffenhofen and Gunzenhausen. Section fourteen stretched from Gunzenhausen to Weißenburg and Kipfenberg. Section fifteen concluded the route from Kipfenberg to Eining.
The Saalburg stands as the most significant attempt to reconstruct the archaeological past of the limes. Construction took place between 1899 and 1907 under the direction of Louis Jacobi. The southwest corner built by Jacobi in 1885 had merlons spaced at wider intervals which were correct for Roman architecture. This section had to be replaced during the full reconstruction probably at the behest of Emperor William II. The new merlons were spaced at medieval intervals instead which is historically incorrect. Dietwulf Baatz later documented this error in his work Die Saalburg published eighty years after the reconstruction began. Wooden watchtowers reconstructed in 2008 based on Baatz's research now stand along parts of the original line. Other sites like Mahdholz feature fully reconstructed sections of the limes wall.
The Upper Germanic-Rhaetian Limes became a UNESCO World Heritage Site in 2005. It forms part of the Frontiers of the Roman Empire alongside other border systems. The designation recognizes its status as an archaeological site with international significance. Preservation efforts continue to protect the earthworks palisades and watchtowers across the 550-kilometre route. Modern maps show the boundary from Rheinbrohl to Holzhausen an der Heide with hiking trails and cycling routes following the ancient path. The German Limes Road allows visitors to travel between key sites including the Taunus-Wetterau Limes region. Various cultural portals provide multimedia dossiers about the history and current state of these ruins. The site remains a testament to Roman engineering and administrative reach into Central Europe.
