Moulin de Kermaux

The Moulin de Kermaux is a stone structure that rises above the prehistoric landscape and sits among the megalithic alignments of Carnac. From this vantage point, you can see the vast network of standing stones and glimpses of the Atlantic coast stretching beyond.

This structure was built at a location where ancient communities erected thousands of standing stones during the Neolithic period. The tower itself was added later to help visitors understand and observe this remarkable prehistoric landscape.

The name comes from an old mill structure that once stood here, and today people use this spot to understand how the ancient stones relate to the landscape around them. Visitors gather to take in the full scale of the megalithic arrangement and appreciate how these monuments fit into the natural environment.

The site is open during daylight hours and offers clear sightlines across the megalithic landscape. The ground is relatively level, making it easy to walk around and explore the area at your own pace.

Researchers have conducted observations from here to trace connections between the stone arrangements and the movements of celestial bodies across seasons. These astronomical patterns reveal how much prehistoric communities understood about the sky and possibly planned their monuments accordingly.
