It is a small, discreet monument, located in the countryside, far from busy roads.
Coming from St-Renan, take the D68 towards Argenton, then at the roundabout, take the D168 on the right towards Ploudalmézeau. About four kilometres after crossing Lanrivoaré, turn right towards the farms of Tréouélan and then Kerarbeugan. At this point take the small road on the left and then the first on the right towards Sandrioné. The road turns between the buildings of a farm and the stele appears in the bend on the right verge. You can park near the monument.
This superb hemispherical stele is carved in a porphyroid granite with large white feldspar crystals from Aber Ildut. With a maximum diameter of 95 cm, it reaches an average height of 90 cm above the ground. The ground being sloping, we can see the beginning of its base. In fact, including the base, it would reach a height of 1.10 m.
This small Gallic burial monument was reportedly moved from a nearby field on an undetermined date.
It should be noted that another hemispherical stele is located not far from there, in the hamlet of Balaren in the commune of Plouguin, which is not part of the Communauté de communes du Pays d'Iroise.
