p to 1965 the old Roman route has been always used to reach Vignui coming from Prèn. Right in Prèn in 1904 excavations brought to light a fibula, a bracelet and a coin bearing the effigy of the emperor Massenzio (currently on display in the Archaeological Museum of Feltre). The Via Claudia went by Vignui and then along the foot of the mount Pafagai. Once entered the San Martino valley, we reach the small village "le Buse" : location of the possible bridge crossing over the stream Stien, about half Kilometre north of the church of San Martino. The bridge is currently located about 800 m higher than the presumed original place. In Lasèn, some excavations brought to light remains of pavement, iron tools, several burial tombs with bracelets, most of which went lost. In this area there was a Castellum (according to Alpago Novello it was located 50 m. higher than the presumed place) of which some spurs have been kept.

he level road reaches Arson, a village where two stones for walnut oil press have been found (very popular in this area). From Arson the road may have reached the striking village of Montagne and from here, uphill and then downhill, to the bridge of Umin, at a point where it crosses the Caorame (Located slightly above is the nice village Le Ave with its remarkable church of Sant'Eurosia). Right in this church, Alpago Novello identifies in the rock cut serving as a support to the church some remains of the Claudia Augusta. From le Ave to Bordugo and then uphill to Toschian towards Can.
