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.

It is an artistic and cultural place. Built on the site of the feudal manor of Plessis-Guériff, the current castle dates from 1722. Partly destroyed during the Hundred Years' War, it has retained a 15th century wing which is still visible today. You can explore the sculpture park and take part in artistic workshops. It is also a hotel. For all information and reservations click here: https://www.chateaudesperes.fr/en

The rock of the fairies, French: Roche-aux-fées, located in the middle of green nature, is simply enchanting. If you are interested in megaliths, you should take a break here. The undisputed largest dolmen in France is also closely linked to the legend of the fairy Liliane. 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.
