Cromlech de Kergenan, Prehistoric stone circle in Île-aux-Moines, France.
Cromlech de Kergenan is a prehistoric stone circle composed of approximately 31 blocks arranged on Île-aux-Moines in the Gulf of Morbihan. Most stones stand between 2 to 3 meters high and form a ring about 100 meters across, with an opening oriented toward the southeast.
This megalithic site was built in prehistoric times and first recorded in the 1800s before being formally protected as a historical monument in the mid-1800s. Major archaeological investigations took place in the late 1800s to study the stones and their arrangement.
The circle reflects how prehistoric communities organized sacred spaces on this island in the Gulf of Morbihan. Walking among the stones today offers a sense of how people gathered and marked important places in their landscape.
Parts of the site are open to visitors while other sections remain on private land and are not accessible. A leisurely walk allows you to explore the visible stones at your own pace and take in the island setting.
Researchers in the early 1900s proposed that this circle might align with other megalithic structures scattered across the region in hidden patterns. This theory hints at how prehistoric societies may have connected their sacred sites across the landscape.
