On the square, you arrive next to the church, whose origins date back to the 17th century. Dedicated to Saint Sulpice, Bourge's bishop, she has two chapels, one in the nord, built in 1611 is dedicated to Holy Virgin, another one (in the south) is dedicated to Saint Nicolas. In the church, you can admire an altarpiece of Sainte Trinité (17th century). Jacques Le Prestre, baron of Châteaugiron, placed his coat of arms in the choir and on the high altar, around 1750. The church has also a bulbous steeple, conceived by Arthur Regnault in 1899 : he is connected to the belfry tower by a square base.
The Ossé's presbytery, located in the north west of the church, is quoted since 1642. A wide part of the actual edifice seems to have been built at this period.
In 2009, during earthworks of the hair salon, workers discovered some slate chests under the ground of the former edifice. There were, actually, tombs from the Merovingian and Carolingian period (481-987). Archaeological services identified three schist chests and four “open ground” burials. A brooch found in a child's tomb made it possible to date it to the 7th century. This recent discover make think that Ossé would be older than we think (maybe the 14th century).
Close to the place, you can observe, in front of Death Monuments, the bread oven, realized in shale rubble over a diameter of three meters. Each hamlet of the commune once had an installation of this type: several families used the oven to bake ten-pound loaves that could be consumed over two or three weeks! This tradition is maintained by the associations during local events.
