The steles of the St-Ergat fountain can be accessed in several ways :
- - Continue the path that leads to the hermitage of St-Hervé.
- - Or take a signposted path from the D 103, between Tréouergat and Guipronvel.
- - Or follow the route below, which has a 1 km long access path, not muddy, as well as a vast parking space :
From the D168, between Lanrivoaré and Ploudalmézeau, and 1 km after the Lanrivoaré exit, turn right towards Tréouergat. Then turn right again 1 km further in the direction of Milizac. Drive 1.8 km and stop on the right side of the road on a large parking space. Follow on foot the hollow path that opens on the other side of the road.
Entrance of the hollow path from the road to Milizac
On this path, 400 m from the road, turn right (on the left the path leads to the hermitage of St Hervé). then 100 m further on, take the path that goes down on the left. Bordering a magnificent landscape, it will lead you to the Saint-Ergat fountain located 500 m away in a wood, near a picnic table.
We do not immediately see the fountain that is hidden behind the three columns. Be carefull, it is a source and its periphery is particularly muddy and slippery.
The three steles attract attention. They are all different. The highest, in the middle, supports a cross. The other two are supports whose top indicates that they have each supported a missing element, cross or statue.
The small stele on the left :
0.74 m high and faces from 24 to 35 cm, this quadrangular Gallic stele has in its corners wide sides of 4.5 cm maximum.
The upper part, 23 cm high, measures 35 x 29 cm.
Less wide, the lower part above ground, 51 cm high, measures 31 x 24 cm.
This division into two parts of unequal dimensions is original. In order to support a wide element, the stele may well have been erected upside down, with its recut base at the top. Since the upper part of the monument has been abraded less regularly than the lower part, it is possible that they were cut back when the monument was placed near the fountain. Only a borehole at its foot could prove this hypothesis if the usual base is missing.
Its top shows that the stele once supported an architectural element with a square base.
The stele on the right :
Much higher than the previous one, this octagonal stele rises 1.05 m above the current ground. We can clearly see the beginning of its 29 cm high quadrangular base above ground. The faces have an average width of 13 cm. At the top, the fixing trace of a circular element is clearly visible.
The central stele :
2.20 m high, this truncated stele has a circumference of 1.13 m at ground level, which is shrinking to 0.98 m at its top. It is not smooth and its size is rough enough to show the roughness of its eroded granite. It was Christianized by the addition of a Celtic cross.
