Via Postumia

Via Postumia is highlighted in light blue. It is reached from Rome at Placentia via the Via Flaminia (dark blue) followed by the Via Aemilia (red).

The Via Postumia was an ancient Roman road of northern Italy constructed in 148 BC by the consul Spurius Postumius Albinus Magnus. It ran from the coast at Genua through the mountains to Dertona, Placentia (the termination of the Via Aemilia) and Cremona, just east of the point where it crossed the Po River. From Cremona the road ran eastward to Bedriacum, the current town of Calvatone, where it forked, one branch running to the right to Mantua, the other to the left to Verona, crossing the Adige river on the Ponte Pietra, the only bridge on the Adige river at that time, and then traversing the Venetian plain, crossing the Piave River at Maserada sul Piave until finally reaching Aquileia, an important military frontier town founded by Rome in 181 BC. The Roman conquest of Liguria depended upon this road, and several of the more important towns owed their origin largely to it. Cremona was its central point, the distance being reckoned from it both eastwards and westwards.

Via Julia Augusta is the name given to the Roman road by Augustus Caesar's efforts starting in 13 BC to merge the Via Aemilia Scauri with the Via Postumia, running from Placentia (modern Piacenza) to a triumphal arch in La Turbie, France. It is later extended to Arelates (modern Arles) joining the Via Domitia, through Dertona (Tortona), Vada Sabatia (Vado Ligure), Albingaunum (Albenga) and Album Intimilium (Ventimiglia).

The ancient Arco dei Gavi still marks the Via Postumia's branch leading to Verona.

From the 15th September 2015, Andrea Vitiello, a pilgrim of Santiago de Compostela, started his great project to rediscover part of the Via Postumia, making it viable for both walkers and cyclists. After a long and careful study, he has rebuilt the online courses, walking and cycling all they long to verify them, found lodgings along the way and prepared gpx tracks for those who want to walk the Via Postumia in total safety, the path is nowadays about 930 km. Andrea Vitiello and his team continue to improve the project that provide knowledge on the group of a famous social networks named "Amici della Via Postumia").
