Citizen science! Two areas I'm interested in and know, SW of UK and Galicia. [dailymail.co.uk]
I lived in that area and can guess where this area is. Copper and tin was extensively mined in the area, so I would have thought that the horizontal line may well be an adit, or a rail line built to transport ores.
I don't see why every straight line has to be an old Roman road!
@Allamanda No, there weren't records made even for mines, which has seen people's garden disappear into an unrecorded mineshaft. Exploratory digs weren't recorded, either, because of the prolific amount of digging that went on.
This is an area immediately adjacent to the Devon Great Consols Mines where large amounts of copper, then tin, was mined. If memory serves me correctly, this area has been listed as a Worls Heritage site.
