Dolmen de Kermario, Neolithic burial chamber in Carnac, France

The Dolmen de Kermario is a passage dolmen opening to the south-southeast, set at the southwestern end of the Kermario alignments in Carnac. Its chamber is formed of large pale grey granite slabs, several upright stones carrying a massive overhanging capstone, with a flat slab resting on lower supports to the left and a loose row of leaning upright slabs to the right. The blocks are mottled with white and grey lichen and soil, and grass grows around their base and in the gaps.

The dolmen was excavated by J. Miln in 1877, and Zacharie Le Rouzic restored it in 1929. It was listed as a monument historique on the 1889 list, one of the earliest protections of megaliths in Morbihan.

The finds from J. Miln's 1877 excavation — a polished axe, flint flakes and pottery fragments — are kept at the Musée de Préhistoire in Carnac. The dolmen opens to the south-southeast at the southwestern end of the Kermario alignments, so it is read together with the rows of standing stones beside it.

The dolmen is located within a protected heritage site and can often be visited through guided tours that explain Neolithic burial practices. Visitors should wear sturdy footwear and be prepared for uneven ground, especially in wet conditions.

The 1877 excavation by J. Miln yielded a polished axe, flint flakes and pottery fragments, all now held at the Musée de Préhistoire in Carnac. The dolmen was listed as a monument historique in 1889 and restored by Zacharie Le Rouzic in 1929.
