Carnac Stones
Bretagne
The Carnac Stones are an extraordinary prehistoric megalithic complex located near the south coast of Brittany, France. Comprising over 3,000 granite standing stones, dolmens, tumuli, and single menhirs, they represent the largest such collection globally. These stones were erected by pre-Celtic peoples during the Neolithic period, likely around 3300 BC, with some possibly dating as far back as 4500 BC. The site consists mainly of four major groups of stone alignments: Ménec, Kermario, Kerlescan, and Petit-Ménec, which originally may have formed a continuous visual landscape. The stones vary in height and arrangement, often forming converging rows and stone circles, illustrating sophisticated prehistoric engineering and ritual significance. The area also contains tumuli with passage graves that once housed Neolithic artifacts. Over centuries, the stones have been subject to neglect and removal for construction, but today they are protected as historic monuments and recognized by UNESCO as a World Heritage Site. The Carnac Stones remain a captivating enigma, blending archaeological importance with local legends, and continue to attract visitors fascinated by their scale and mystery.
