The milestones
Unlike other Roman roads, direct proof of the existence of the Via Claudia Augusta is found in two very important milestones probably laid in the spirit of commemoration. The milestones provide exhaustive testimony as to the name of the road, its date of completion, who ordered its construction, its total length and the very rare fact of its “precedent”. The information is so exhaustive that it creates some problems in identifying its exact route; while the northernmost reference point of the road is accepted as being the area on the Danube near Augusta, each milestone gives a different indication of the southern end: the Po River, near the present-day Ostiglia, in the stone found in Rablà/Rabland (South Tyrol), and Altino (Venice), at that time, a major harbour on the Adriatic, in the milestone of Cesiomaggiore (Belluno, Italy).
The archaeological investigations have led historians to identify a bifurcation of the Via Claudia Augusta to Trento, and a single course from Trento to Bavaria.
Here are the inscriptions on the two milestones:
