This concerns two milestones without epigraphy - without engraved information - which form part of the secondary roman road that connects the great roman city of Chaves (Portugal) with Xinzo da Limia. This route of communication followed a path similar to the current A-52 dual carriageway, and could have been a stage of a long distance roman road that connected Aquae Flaviae (Chaves) with Iria Flavia (Padrón), crossing the valleys of the Támega, Búbal, the plain of A Limia, the valley of Arnoia and the area of the Miño.
