Based upon documental, oral and historiographical archaeological data, it has been established that the layout of the ancient Roman road running across Pindo, Ardãos, Senhor do Bonfim and Seara Velha corresponded to a section of the Roman trajectory connecting Braga to Astorga via Chaves – the XVII Roman road listed in the Itinerarium Antonini.
This transport connection served several Roman settlements alongside the important mining region of the Terva Valley and presented a balanced topographic layout, as documented by preserved remains on its circuit.
At least, six milestones have been indirectly associated with its itinerary and they document the continuous maintenance works conducted on the Roman road, being the oldest works from the Augustan period (27BC-14AC) and the most recent from the emperor Adrian time (136-137).
The fragments from the Augustan milestone are stored at the TVAP Interpretation Centre. The milestone was reused as a sarcophagus in medieval times, however still exhibits the following inscription: IMP (eratori) CAE|s(ari)/AUGUSTO|O| A| BRAC|ARA M.P|LXV. The item was recovered from a hillside in Lapabar, Sapelos, nevertheless, it is believed that it must have originally been located at the Pindo area, in the mountainous region of Cervos, Montalegre.
