A legend has been perpetuated for generations on this 25 meter high stone planted on a ridge (in patois we say that it rocks). A little step back in time... Saint-Ghislain completes the construction of its abbey. The devil decides that he will take advantage of the inauguration day to destroy the abbey and its occupants, by throwing an enormous stone found in the Pyrenees at the community. An angel warns Saint-Ghislain of the imminent danger weighing on the abbey. He gathers as many pairs of worn shoes as possible, which he slips into a huge bag and takes to the road to meet the evil one. Coming across a poor fellow in rags with holes in his shoes at this place, the devil, quite exhausted by the heavy load, questions him: “Is the abbey of Saint-Ghislain still far away? ". - “I’m coming from there, if it’s far!” » replies the old man while emptying his bag, filled with threadbare shoes, in front of the devil. Discouraged and disappointed, Satan preferred to give up, dropping his heavy stone on the ground and walking away blaspheming, fooled by the subterfuge. An hour and a half. N.B.: some historians say that this is the legend of Saint Remacle, during the construction of Stavelot Abbey. You are therefore free to substitute Remacle for Saint-Ghislain since this substitution does not modify the spirit of the story. In both cases, the devil is defeated.
