From the end of the Middle Ages, villages started to emerge with the gradual setting up of traffic routes. Some were narrow and connected the villages to the fountains and fields, others were wider and more passable, like this one linking the town to Keralloch. The country folk dug out the central part. Earth and stones were used to build the embankments, which were then planted with trees, here centuries old. They were known as sunken paths not only because of their construction technique. Many of these sloping paths, washed out by the rains, have become so dug out that they sometimes reach several metres in depth and expose the granitic subsoil or veins of underground water.
