June 23, 2026, Mégalithes de Saint-Just

Sacred space, Saint-Just was frequented by Neolithic people for several millennia. Our distant ancestors settled on these dry moors to form a major complex of megalithic monuments, the second most important in Brittany, after Carnac. On a route of about 6km you can discover various alignments bearing strange names often linked to a local legend. The path can be walked, run or even cycled across a moor that offers no shade or shelter. A magical and fascinating place in every respect

Just on the path to the right (you may have to get off the bike) are the magnificent Menhirs of Monteneuf. Menhirs are Neolithic monuments: large rocks that ancient people erected vertically either to indicate the path or as a tomb.

The covered alley of Tréal or also called Grotte aux fées according to a legend is an isolated burial site, located at the top of a hill called "La butte de Tréal" or "the rock of Tréal".
