Located in the hamlet of Thioles, near this river, the menhir generated the toponym « Pierre fiche », without ambiguity. This name, common throughout France, should be compared to « Pierrefitte » or other phrases such as pierre fichée, pierre plantée, pierre levée, pierre longue… Erected on the edge of a cornfield, the menhir measures 3.80 meters in height, about 0.50 meters in thickness and 1.30 meters at its widest. The stone is said to be sunk several meters into the ground. Nothing allows us to confirm the dating of the Simandre menhir, but its shape brings it closer to Burgundian examples dated to the Middle Neolithic (4200 to 3600 BC). Ancient mentions from the 12th century reveal the existence of two other menhirs, neighbours of Pierre Fiche but which were reportedly removed in the 18th century. It could therefore be not an isolated monument, but part of an alignment or a more complex ensemble. There is also mention of a third menhir near the nearby mill. And also of a dolmen that disappeared long ago, near the village of Chavannes-sur-Suran, and whose tiled roof would have given its name to the hamlet of Thioles… In Simandre, it is told that passing fairies planted three cattails in a field which turned into enormous stones… The menhir has also become a place of popular belief linked to fertility: couples wishing to have a child would rub themselves against the stone and pilgrims would scrape it to swallow the dust. The oldest monument classified as a historical monument in the department (March 6, 1888), the megalith is private property but remains easily visible from a hiking trail. https://patrimoines.ain.fr/n/menhir-de-pierre-fiche-a-simandre-sur-suran/n:320
