Numerous Breton legends surround the stone. One of the most famous tells that the menhir sinks a little deeper into the ground each year, and that its complete disappearance will signal the end of the world. Another legend sees it as a divine sign that separated two feuding brothers and gave the field the name "Champ-Dolent," or "Field of Sorrow."

South of Dol-de-Bretagne rises the Menhir du Champ-Dolent, a mighty granite block from the Neolithic period. At almost ten meters high, it is one of the largest surviving menhirs in France. Its weight is estimated at around 100 tons, and it was probably extracted from the immediate surroundings. Its original function remains unclear to this day—researchers suspect ritual or symbolic purposes, perhaps even an astronomical alignment.

It is the most imposing menhir in the region, standing almost 10 meters high. Its contour is 8.70 m on its widest part. According to legend, two brothers and their armies clashed there. The celestial hand separated the warriors, a rock then fell from the sky, and penetrated heavily into the earth. Since then, this menhir sinks steadily an inch per century; the day when the stone of the Champ Dolent is completely buried, it is said that the world will end.
