As soon as 1803, Talensac was an independent parish which also included the village of Le Verger. The first church was replaced and rebuilt around 1703. But this church, dedicated to Saint-Anne, was devastated by a fire in June 1872. Another church was then built (actual church). It has been consecrated in 1882 by the archbishop of that time.
Judicaël and Erispoë, kings of Brittany, had a residence from the 7th and 9th century in Talensac. Erispoë lived in the village of the "Châtellier" next to the road of Breteil. This fortification was protected as it had moats. The 2 November 857, Erispoë is assassinated in the church of Talensac by Salomon, his first cousin, who didn't want Erispoë's daughter to marry the son of Charles le Chauve. This would have brought into play the lands of Salomon and the independence of Brittany faced to West Francia, but also all the chances of Salomon to access to the throne.
In 1152, Guillaume I's spouse gave Saint-Jacques de Montfort abbey, the taxes of Talensac and the mill of the town to monks. The son of Guillaume I and of Amice de Porhoët, Godefroy de Montfort, left the "le pré au Comte" in 1171.
Around 1372, the castle of the "Châtellier", property of the Bintin family, is devastated.
In 1697, Jeanne-Françoise De Massuel, Lady of the Bois-de-Bintin, married the Lord of Belin, Mathurin Lesné, in Talensac. Him and his spouse lived in the castle of "Bédoyère", an imposing residence from the 17th century.
The castle, badly preserved during the different periods it went through, was demolished around 1920.

The grès Saint-MéenEdit

In the forest of Montfort-sur-Meu, at the place called "Le Bois de Saint-Lazare", we can see at the edge of an old oak, the menhir of the Grés Saint-Méen. This menhir is classified Historical Monument. According to the legend, Saint-Méen had built the town of Talensac. There are two stories about this legend.
The first version says that Saint-Méen was travelling with his followers and he saw a hill full of vegetation near the banks of the Meu river. He liked the landscape and so he decided to stay a few days at this place. After crossing a ford, he said to a monk, at the same time he thrown his battle axe he had in his hand: "Where this battle axe will fall is where Méen will build". And the axe felt at the exact place where the church of Talensac is today. Saint-Méen kept his word and cleared with help from his companions, a space big enough to build a chapel and a few shelters for him and his apostles. Then he spread the good word to the pagans in the surroundings. Many people listened to his voice and settled around the chapel. According to this first version, this is how appeared the town of Talensac.
The second version says that the Grès Saint-Méen was a kind of menhir upside down that had traces of acorn cups on the top. During the 6th century, after sharpening his battle axe on this stone, Saint-Méen said "Where this battle axe will fall is where Méen will build". Then he built the church of Talensac, 1.200m further long, where the battle axe felt. According to the same version, the stone was used as an altar for the immolation of human victims. Saint-Méen might have been attacked by one of his former followers. He managed to avoid the knocks of his disloyal apostle. But this last, while trying to kill Saint-Méen, hit the stone which felt right on him. We say that his body is still underneath.
