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

Located in the town of Bain sur Oust, it is the place of the meeting of Nominoë and Conwoïon who brought the body of Saint Marcellin from Rome to the Saint Sauveur de Redon abbey. This trèviale chapel fell into ruin, the primitive Romanesque building was rebuilt from 1945

The Etang de Val is also known as the Etang de Saint Just. At one end of the pond is a dam where two mills used the energy it provided. The view from here is breathtaking.
