The church of Saint-Pierre and Saint-Paul has stood in the center of the village since the end of the 15th century, according to historical data. It includes a polygonal choir and an east-facing nave. The religious building was enriched with two chapels and an aisle in the following two centuries. The bell tower, located in the center of the nave, was demolished and replaced by a tower in 1840. The church houses several statues from the chapel of Saint-Nicodème de la Grande Touche in Guilliers, such as that of Sainte-Apolline, dating from the 16th century.

Tirains run fairly often (about every hour on an ordinary Weds mid-afternoon when I was there). You can get to Rennes in one direction and Lamballe (? - check ?) in the other. From Rennes you can get to lots of other places, and I used this method to quickly move from inland to coastal Brittany. Using the machine, it is easy to buy a through ticket and provided you stay on TER trains, you can bring a bike without reservation (but subject to space/train manager's say so on busy times). I didn't see a lot of commerces in the vicinity of the station, but likely one could find stuff if one was in need -- looks like centre-ville is about 1 K level ride away.
