Via Julia Augusta
The Via Iulia Augusta was a Roman road that was built in the reign of the Emperor Augustus.
It led from Vada Sabatia ( Vado Ligure ) along the Ligurian coast on Albigaunum (Albenga ) and Albintimilium ( Ventimiglia ) and by the Maritime Alps west to Arelate ( Arles ) in Gaul (now Provence).
Possibly also a section of road was considered part of the Via Iulia Augusta, which led from Iria on the Postumia southwest towards Vada Sabatia; but this section could have been the continuation of the Via Aemilia Scaura that ran along the eastern Ligurian coast over Genoa after Vada Sabatia.
Formation
The construction of the Via Iulia Augusta was made possible after the people of the Maritime Alps were conquered by the Romans. Until then, the land connection between Italy and Hispania through the much more northerly Col de Montgenevre and the subsequent Via Domitia was maintained. The establishment of the rule over the Maritime Alps, followed by the construction of a road through simpler and without any real difficulties manageable terrain, which also brought about a significant reduction in travel times with it: Thanks to the Via Iulia Augusta was reached Arles - the Cursus publicus with 70 kilometers per day assumed for four horses Jump - arrive within eight days, an army was within 27 days on the Iberian Peninsula.
Course
The Via Iulia Augusta was the extension of the Via Aurelia and the Via Aemilia Scaura along the Mediterranean coast. Therefore, it was later considered as such and - as the coastal part of the Via Aemilia Scaura - also called Via Aurelia ( For the exact course qv).
From Aquileia a Via Iulia Augusta led northward over Iulium Carnicum and the Plöckenpass to the Drau valley where they at deer - after ( castrum First broadcast of " dux Ursus " is the name of the street station still unknown) informed and Aguntum after Veldidena or via Teurnia Virunum and Iuvavum led. At the same naming occurred because Aquileia is the birthplace of Julia's son Tiberius.
In the Antonine Itinerary it is run as a shortcut to Veldidena over the Plöckenpass and Aguntum and seen the abbreviation to date ( 1 /06) route via the Eisacktal. The distance information between Iulium Carnicum ( Zuglio ) and Littamum ( Innichen ) fit only for the route over the Kreuzbergsattel ( Zuglio - ( Sutrio ) - Forni Avoltri - San Nicolo - Innichen ) and this will be the abbreviation for the route across the Plöckenpass. In addition, there is a presumption that the route Aquileia - Virunum about Iulium Carnicum - castrum Ursus - Teurnia led and the route through the Canal Valley was beaten only in the 2nd century to Villach. So it can be assumed that the specification according to the Antonine Itinerary for the total distance " of Aquileia on the Danube mp CCLXXII "= 402.5 km ( too short), right on CCCLXXII mp must be, and the Reichsstrasse over the Plöckenpass the Drau ( deer / castrum Ursus ) led or via Teurnia, with the Straßenabzweigung after Immurium ( Moosham ) Iuvavum (Salzburg) in seabed - Santicum (Villach / meetings), and later erected with the diversion the Val Canale - Feldkirchen, with the Straßenabzweigung after Immurium - St. Peter am Unterbichl and Karnburg, went according Virunum. The distance Aquileia - Virunum is CLXXXVII mp or 125 Gallic marker from.
The road stations were located in: Tricesimo ( Tricensimum ) Zuglio ( Iulium Carnicum ) with the junction " viam Belloio " Weidenburg iG ( Larice ) Greifenburg / Radlach in the Drau Valley ( Bilachium ) Baldersdorf (....? .... ) and Villach / meeting ( Santicum ). The route Virunum - Lauriacum ( Enns on the Danube ), with CLXXXV mp led over the Görtschitztal with the first road station in Wieting (Carinthia ). The later road over Friesach and through the gorge to the north was then in younger street directory, in the Tabula Peutingeriana was added as well as at Treibach ( Matucaio ) branching and extending over Gurktal new road to Immurium. The data for the track Aquileia - Virunum by the Canal Valley can be found also only in the Tabula Peutingeriana.
