Equestrian circuit n°4 - Lanrivoaré - Tréouergat

Saint-Renan municipal campsite parking lot (29290)

Located at the bottom of the Traon Bouzar, the Vallon Sourd, the Saint-Ergat fountain is a natural spring that has always been frequented by hundreds of pilgrims suffering from rheumatism. The three columns, reused Gallic stelae, bear witness to an ancient cult at this site, later linked to Sant Ergad when he became the patron saint of the Tréouergat parish.

The story goes that when the fountain was not decorated with any stonework, a woman from Loukournan (Saint Renan) suffering from rheumatism recommended herself to sant Ergad and entrusted a relative with a mission: to go to the fountain, empty and clean it. As soon as her emissary set to work, she felt a slight improvement, which was soon confirmed. Similarly, a young boy from Tréouergat suffering from "languor" was miraculously cured, and his grateful parents had a cross erected near the fountain.

Last but not least, we all know the legend of the Lords of Peñc'her, on whose land the fountain once stood. Tired of seeing the pilgrims parade past, they decided to fill in the fountain. Almost immediately, one of the family members fell ill, followed by several others. They promised to restore the site and honor it with a carved stone representing their coat of arms as a sign of repentance. This they did, obtaining an immediate collective healing.

The Costouarné cross (16th c.) is 3.50 m high, with a cubic base and a flared shaft.

The ruins of a chapel and the hermitage known as Saint-Hervé still stand on the cross.
