The dolmen stands in the middle of the village, close to a house. It once had a long passage and measured 27 meters in length. The cover plate weighs approximately 40 tons. For a long time, it served as a barn.

While cycling through the countryside, be sure to visit the Alignements de Sainte-Barbe. These impressive megalithic stones, arranged in a particular alignment, are a fascinating historical site dating back thousands of years. Situated in a peaceful rural setting, the stones are easily accessible by quiet cycle paths, and the surrounding landscape adds to the charm.

The two comic book heroes Asterix and Obelix, who are very popular not only in France, discover Brittany and the huge stone rows from ancient times that can be found there on their very own "Tour de France" (under the title "Le Tour de Gaule", volume 5 of the French edition, but volume 6 in the German edition). The explanation given to the two travellers for the origin of the megalithic culture is, however, too simple: people say that the soil is so bad that only stones grow there; this can be read in the comic.

The Alignement de Kermario may not have the most megaliths, but it does have the largest and most impressive ones. All megalithic fields are fenced off, but a beautifully laid out and well-signposted circular path opens up and connects the megalithic fields and allows you to see the stone witnesses of history from the path. Don't forget that it doesn't cost a cent to walk the paths.

The stone rows of Sainte-Barbe are located at the northeastern exit of the town. Dozens of stones stand or lie in several rows, the largest around 5 meters high. A calm place worth seeing.

This dolmen would have long served as a stable. It is made up of nine pillars and the covering slab weighs more than 40 tonnes. Access to the dolmen was formerly via a long corridor of 27 meters which no longer exists.
