This Roman road, also known as the Antonine Itinerary (Bracara Augusta - Lucus Augusti), dates from the 2nd century C.E. and connects the former Roman conventus (administrative districts) of Braga and Lugo. It was the longest road in the northwest of the Iberian Peninsula, about 500 kilometres long. Roman roads were built by the Roman Imperial State in order to articulate the territory and to join the capital cities of the different Conventus Iuridici (administrative capitals of the Roman era). These ancient roads acted as an important backbone and a key factor in socio-economic and commercial dynamization. In addition, they had many other functions: strategic and military (defence, transportation of troops), fiscal (tax collection, people and goods control) and contributed to the reorganization of the territory. It connected the cities founded by Emperor Augustus in Gallaecia, Bracara Augusta (Braga) and Lucus Augusto (Lugo), reaching Asturica Augusta (Astorga), in order to provide the troops in the northwest of the Iberian Peninsula with basic goods (wheat, wine, salt-preserved foods…), which gave the infrastructure a great commercial value.
