Located at 20 km in the West of Rennes in the perimeter of the second suburb of Rennes, Talensac is crossed from the West to the East by the brooks of Guillermoux and of Bignons which form the Barillais, the Serein and the Rohuel and then the Chèze which are confluents of the Meu river.

It is surrounded by Montfort-sur-Meu, Bédée, La Nouaye, Breteil, Pleumeleuc, Iffendic, Saint-Gonlay.

In 1152, Guillaume I's spouse gave Saint-Jacques de Montfort abbey, the taxes of Talensac and the mill of the town to monks.

In 1697, Jeanne-Françoise De Massuel, Lady of the Bois-de-Bintin, married the Lord of Belin, Mathurin Lesné, in Talensac.

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.

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.

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.

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.

It successively belonged to the family Haloret, De l'Estourbeillon and then Le Guern.

The fountain, located near the town centre, has, according to the local tradition, the power to cure eyes.

The Eminescu park offers an exceptional view on the valley of the Meu river.

Starting point of pedestrian paths, this park has picnic areas and playgrounds.

It offers a nice panorama on the villages of Monterfil, Le Verger and Treffendel, but we can also see a bit of the city of Rennes.
