Origin and history

The Pierre au Trésor de la Triée, also known as Menhir de la Triée, is a megalithic vestige dating from the Neolithic, discovered in Notre-Dame-de-Riez, in the Vendée department. This monument is presented in the form of an elongated block of 2.50 meters long, initially buried under 80 cm of earth. During excavations conducted by Marcel Baudouin, sculptures were identified on its surface, including a human foot representation, as well as bowls and cups, characteristic elements of megalithic art.

Ranked as historical monuments by order of 12 May 1924, the menhir experienced several movements. After its discovery, it was first erected near the monument to the dead of the commune, before being transferred to the garden of an individual, in the Triee district. These trips reflect the challenges of preserving and valuing the local heritage, while highlighting the challenges of in situ conservation of megaliths.

Historical sources, including Bertrand Poissonnier's work in The Prehistoric Vendée (1997), confirm the archaeological importance of this site. Menhir illustrates the cultural and ritual practices of Neolithic in Pays de la Loire, where communities erected stones for probably symbolic or commemorative purposes. Its present state and its approximate location (140 Route des Garateries) recall the limits of knowledge about these monuments, often displaced or reused over the centuries.
