As part of Brittany, the city of Talensac is more precisely located in the department of Ille-et-Vilaine.
Talensac comes from the Latin "Tallentius" or "Talutium" (embankments). The suffix "ac" indicates a Gallo-Roman.
The kings of Britain and Judicaël Erispoe (the latter Nominoë son) had to Talensac a residence, the seventh and ninth centuries. The latter resided in 852, he seems to "Chatelier" about 600 meters from the town, along the road BRETEIL. This castle Talensac should be strengthened as it had a double enclosure ditches.
The castle "Chatelier" seems to have been destroyed around 1372. He belonged to the family De BinTin, which was arming "of gold to the sand engreslée cross between four fleurs de lys of the same" (Seal 1306). The family Porteu The Morandière was rebuilt in the nineteenth century.
Around 1810 Talensac had 5 water mills in operation: Le Chatelier, Le Guern and Tréjouan on Meu Le Coudray and the Bedoyere the Serein. These mills for grinding grain allowed everyone to get the flour to make bread, the staple food of the time. It was in 1944 that went out this activity in the municipality.
The cemetery was once located around the church. Around 1930, he was transferred street "cemetery" now renamed the street "The Hunaudière". Near the church, on the site of the old cemetery is still a cross storied granite, appearing on one side a Christ and the other a Pieta with four characters placed two on each side; four angels are standing along the shaft and four others are in adoration at the top.
The fountain Saint-Lunaire, which saw the church was once a place of pilgrimage for people with eye and threatened with blindness.
There was the territory of the parish of numerous chapels, the most important was that of Le Verger. Another example is that of Bransahier (already mentioned), the Bedoyere, Rolland La Touche, Holly, Hermitage (there was one located in the chapel Bachelor Oresve) of Fontenelle, Saint-Laurent-les -Guérets (dependency of the priory of Saint-Lazare) of Guillermoux (Guihermoulx), St. Joseph (wood BinTin) and Bonnais (in Orchard).
