The current church of Corsept is not the first church of the commune. Several constructions have succeeded each other over the centuries. The discovery of the Carolingian baptismal tank seems to confirm this.
Today’s building was built on the former church of Saint-Martin – Saint-Marc dating from the early 18th century. Its exact age is probably indicated by the sundial that adorned the gable on the south side of the transept and bears the date of 1726.
The church is a mixture of Romanesque and Gothic style. Its main characteristic is its low bell tower in slate bulb and in the shape of a Latin cross. The bell tower was probably built between 1804 and 1807 during the restoration of the churches in the aftermath of the Revolution. The latter probably replaced an old bell tower that was at the crossroads of the naves (according to an old painting that was in the castle of La Verrie). From the outside, it looks like a Breton church, stocky, gathered on itself to escape the grip of the winds. It is oriented east-west, parallel to the course of the Loire, like the ancient churches. The choir is in the East (East) and the bell tower in the West (West).
Inside, one can notice various riches such as statues, altars, the ex-voto, a baptismal tank and a terracotta tank.
The church has undergone several restorations. That of 1923-1925 resulted in the removal of the steps and the paving of the entrance to the church was put on the same level with the road. The last restoration work was carried out by volunteer parishioners from 1992 to 1995.
