Dolmen de la Planche à Puare is a dolmen located in L’Île-d’Yeu, in the French department of Vendée.
The building was excavated for the first time in 1833 by Augustin Auger, justice of the peace, then a second time by Marcel Baudouin in 1909. It was classified as a historical monument in 1889.
Under the paving of the transept crossing, Auger discovered a number of human bones, mainly long bones (tibias, femurs, humerus), carefully arranged lengthwise, without any associated archaeological material.
