The Saint-Michel mound is a megalithic mound located in Carnac in the Gulf of Morbihan.
The mound is located in the town of Carnac in the Morbihan department.
In December 2012, following the collapse of several stone walls, the site was closed to the public. In 2014, repair work was carried out and the site has become accessible again.
The Saint-Michel mound is made up of a mound of earth and stones 125 meters long, 50 meters wide and 10 meters high. Explored in 1862, the researchers found a central vault containing fairly prestigious funerary furniture: polished axes in jadeite and fibrolite, and a necklace of pearls and variscite pendants. Around 1900, archaeologist Zacharie Le Rouzic again excavated the Saint-Michel mound and discovered a second dolmen and fifteen small stone chests, revealing the complexity of this monument, probably reserved for a princely elite and built around 5000 BCE.
