The holy Aubert of Avranches was bishop of the Norman city of Avranches in the 8th century. According to Christian tradition, he founded the first sanctuary on the rock of the later Mont-Saint-Michel. According to legend, the Archangel Michael appeared to him several times, urging him to build a church on the then Mont Tombe. After initial hesitation, Aubert followed this command and had a chapel built, which became the origin of the famous pilgrimage site of Mont-Saint-Michel. Aubert is venerated as a pious bishop. His feast day is September 10th.

Many visitors run their hand over the chapel's granite wall or briefly place their hand on it. It is said to bring: • Good luck, • Protection on journeys, • or the fulfillment of a wish. However, there is no official historical source to document this custom. It is a local tradition passed down by visitors and tour guides – similar to many pilgrimage sites.

Who was Saint Aubert? According to legend, the Archangel Michael appeared to him in a dream three times in the year 708 and instructed him to build a church on the then Mont-Tombe. Aubert considered the first two apparitions to be dreams and ignored them. On the third occasion, Michael is said to have become impatient and touched him on the forehead with his finger – so forcefully that a hole was created in his skull. This hole, supposedly created by the archangel's finger, is still shown today in the Basilica of Avranches. Only then did Aubert begin the construction of the first sanctuary, from which Mont-Saint-Michel later emerged. The statue therefore shows him as a bishop: • with a mitre on his head, • in bishop's vestments, • with his right arm raised in a gesture of blessing, • with the crozier on his shoulder.

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.

A hike through sunken country paths. The highlight of the walk, the menhir, is worth the detour!

A forgotten part of Mont Saint-Michel, this chapel on the northwest side of the island. At low tide you can easily walk towards this chapel that is not otherwise open to visitors, but is nevertheless beautifully situated on the rocks below the famous monastery.

In the Netherlands we know them as 'Hunnebedden', but here in Brittany you will also find them next to the Menhirs.
