La Roche-aux-Fées Dolmen
Highlight • Monument
The construction of this monument undoubtedly dates back to the Neolithic period, i.e. around 2,000 years before our time. So far, researchers have not found an explanation for exactly how it was built. With its 19.50 meters length, six meters width and four meters height, the structure is more than impressive. And when you consider that some of the stones, which weigh more than 40 tons, come from several kilometers away, you can rightly ask yourself how the people of that time managed to transport them here. This mystery gave rise to a legend: it is said that the impressive structure was built by Viviane and her fairy friends.

Tips from the Community
With nearly 20 meters long, 6 meters wide, and 4 meters high, the Roche-aux-Fées remains the largest dolmen in France and one of the best-preserved in Europe. It is composed of a schist-covered passage formed by four chambers whose meaning has not yet been revealed. Although the construction of this monument dates back to the Neolithic period, around 2000 BC, specialists remain perplexed about its construction method. The site is impressive. And when you know that some stones weighing over 40 tons come from several kilometers around, you wonder how the inhabitants of the time managed to move them there. Such a site could only inspire stories, legends, and beliefs. One of them tells that the fairy Viviane, aided by fellow fairies, would have built this imposing monument... in one night. Another concerns lovers: to know if their union will last, couples must walk around the Roche-aux-fées, each in a different direction, and count the stones. If they find the same number of stones, their future will be bright! Through a mysterious alignment during the winter solstice on December 21st or 22nd, the sun rises facing the entrance of the dolmen. At that moment, the light rays magically illuminate the stone located at the back of the covered passage. Access is free and open. The small surrounding roads are charming and quiet.
