About
About Conguel Dolmen — Quiberon
Conguel (Late Neolithic c.3500–3000 BCE) perches on the windswept granite Pointe du Conguel, the narrow isthmus linking Quiberon peninsula to mainland at Saint-Pierre, a 3-m passage grave with small polygonal chamber 2.5 m partially inset under a 12-m round mound kerbed, now truncated by coastal erosion. Excavated by Le Rouzic 1895 and R. Pollès 1970s, it yielded Late Neolithic corded Bell Beaker sherds and microliths showing peninsula transgression ritual. Its isthmus location mirrors the neck-control symbolism seen at Baroña.
Why it mattersOnly proven isthmus passage grave in Morbihan; Quiberon peninsula territorial marker.
