Origin and history

The menhirs of Kerharo Vian are two megalithic monuments located in the town of Plomeur, in the Finistère department, in Brittany. They date from the Neolithic period, an era marked by erect stones, often associated with ritual or funeral practices. These menhirs were discovered in 1978 during the exploitation of a sand quarry, revealing their presence buried under the dunes. Only the top of the largest menhir was visible, indicating their seniority and progressive integration into the natural landscape.

The discovery of the menhirs led to their registration as historic monuments by a decree of 17 June 1983, thereby recognizing their heritage value. The largest of the two menhirs is 2.50 metres high and has an oblique slit near its top. Other stones, found lying nearby, suggested the existence of a possible megalithic alignment. However, sand mining has unfortunately destroyed any archaeological context, making it impossible to thoroughly study their original layout.

The menhirs of Kerharo Vian illustrate the challenges of preserving heritage in the face of modern human activities. Their protection as historical monuments allows them to study and value them as witnesses to the cultural and religious practices of neolithic societies in Brittany. Their location in Plomeur, near Quimper, makes them remarkable elements of the rich megalithic heritage of Finistère, a region particularly dense in prehistoric sites.
