The church was built in the 12th century near the Château du Tiercent, without a nearby village until recently. It can be assumed that the creation of the parish was an initiative of the local lords. Source: https://fr.wikipedia.org/wiki/%C3%89glise_Saint-Martin_du_Tiercent

A popular hiking destination, the Rumignon woods are connected to the grounds of the Château de Saint-Aubin-du-Cormier by the GR 37 long-distance footpath. For centuries, the medieval castle was a symbol of Breton independence. Once comprised of ten towers forming a vast enclosure, the castle was destroyed in 1490 by King Charles VIII, who had the keep cut in two.

Beyond the Poste d'ouée straight ahead, you arrive at a military area (restricted access), a red hatched zone on the map. The dike on the right, overlooking the pond, is reserved for fishermen (dead end!).
