The Gallic stele dating from 300 to 200 BC stands to the east behind the choir of the Romanesque church of Saint-Tudy. It was probably the grave of an important Gallic figure. A truncated cone-shaped stele with longitudinal grooves, it was flattened at the top to receive offerings in days gone by.
Later, towards the Middle Ages, it was Christianised by the addition of an octagonal cross.
