Tips from the Community

Fabrice Rigalleau
March 24, 2026, La Roche-aux-Fées Dolmen

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.

The first castle of Châteaugiron was built in the middle of the 11th century by Anquetil, a Norman knight, who had received the lands from Alan III, Duke of Brittany. The oldest part of the current castle is the castle's Romanesque chapel dating from the 12th century. Probably in the 13th century, Châteaugiron castle was rebuilt as a stone fortress. Currently the Château de Châteaugiron fulfills several functions; its main body is used as a town hall, the other parts are used as offices and the independent keep is used for exhibitions.

Four of the six original towers of Château de Châteaugiron have been preserved. This medieval fortress houses the Gourdel museum.
