Les Trois Pierres dolmen

Les Trois Pierres is a Neolithic megalithic structure with an inner chamber situated beneath carefully arranged stone blocks. The construction consists of large stones fitted together to create a protected interior space that has survived for millennia.

The site was built approximately 5000 years ago and belongs to a wave of megalithic construction that spread across western Europe. This period shows when people began creating permanent structures intended to outlast generations.

The structure belongs to a network of megalithic monuments across the region, showing how early communities worked with stone to create lasting constructions. These sites served as gathering places that connected people to their land and ancestors.

The site is located in rural surroundings and remains accessible throughout the year without special requirements. Visitors should wear sturdy footwear and exercise caution in wet weather, as the stone surfaces can become slippery.

The inner chamber has been preserved under the weight of several tons of stone, showing how precisely the builders planned their structure. This hidden geometry makes the site an example of early architectural planning.
