This is a dolmen with a corridor, dating from the Neolithic period and serving as the floor of the south transept of the Chapelle des Sept-Saints. The six stones are divided into two granite tables supported by four vertical slabs. This dolmen is nothing more than the skeleton of an ancient tumulus, a grave covered in earth.
