Origin and history
The dolmens of Roh-Vras, also known as dolmens of Kerran, form a megalithic ensemble located in Saint-Philibert, Morbihan. Originally, three corridor dolmens, included in the same terrace, composed this neolithic site. In 1886 Félix Gaillard searched the south dolmen, describing in 1892 a structure composed of supports and stone tables, one of which had a remarkable pavement in one or two large stones.
In 1896, Jean-Baptiste Piketty acquired the stones of the third dolmen to make it a family grave, despite the opposition of Zacharie Le Rouzic. Dismantled and then transported by rail, this dolmen was reconstructed in the cemetery of the Long Reages in Meudon, where it is now known as the dolmen of Ker-Han. During this disassembly, engravings (a studded axe and a rectangle with rounded corners) were discovered on its slabs, as well as archaeological furniture including vases, axes, and callai trim.
The two remaining dolmens at Saint-Philibert were classified as historical monuments in 1927. The excavations of Gaillard and Le Rouzic revealed funerary objects (bones, flints, pendants) today preserved at the Museum of Prehistory of Carnac. The site illustrates neolithic funeral practices and the challenges of preserving megaliths, between looting, reuse, and heritage protection.
