According to the legend Saint FlodoBerthe, a nun from Faremoutiers Abbey in the 7th century decided to establish a chapel between Faremoutiers and Saintes. Not finding a stone to carry out her project, she shared her wish with her sister Sainte Aubierge, the latter brought back the menhir in her apron, the shape of which evokes a church gable, she let go of the corner of her apron and the stone stuck. in the Maillard pond in its current place.

The menhir is made up of a large sandstone slab 3.50 m high with a width at the base of 2.40 m and an average thickness of 0.50 m. It has an oblique groove approximately 2 m long by 4 cm wide on its face and obtained by staking to a depth of 1 cm. An excavation carried out at the foot of the menhir did not yield any archaeological material2. Sainte-Flodoberthe and her sister Sainte-Aubierge both built their respective chapels in Amillis and Saint-Augustin. Sainte-Flodoberthe having finished building hers wanted to offer a beautiful stone to her sister but on the way she met the latter who came to tell her that she had also completed her project. Sainte-Flodoberthe then abandoned the stone on the spot. As for the groove, it would have been made by the handle of Sainte-Flodoberthe's distaff which spun while walking with the stone under her arm2.
