Conche Verte, Neolithic menhir in Olonne-sur-Mer, France
The Conche Verte menhir stands 3.15 meters tall and measures 3.45 meters in length, constructed from micaschist stone material.
Marcel Baudouin conducted archaeological excavations at the site in 1901, discovering a polished amphibolite axe fragment and limestone wedging stones.
The menhir represents prehistoric megalithic construction methods and serves as a regional marker of ancient settlement patterns in coastal Vendée.
Visitors can reach the menhir through a 3-kilometer hiking trail starting from the Menhirs parking area on the Olonne forest road.
A layer of blackened earth found beneath the menhir indicates the sand dunes formed after the megalithic structure was erected.
