The construction of this church began in the 10th century. In the 11th century a large fire destroyed a large part of the church, but later the church was rebuilt. It was rebuilt in the 16th and 17th centuries, possibly thanks to the generosity of the Dukes of Brissac. It has been a historic monument since 1974. There are statues of gargoyles on the facade which are quite remarkable. For mass it is the 1st Saturday of the month at 6:00 p.m.

The old parish church of Martigné ended with a straight apse with a large mullioned pointed arch window. An altarpiece placed in the 17th century had blinded this bay. The current church was built in 1867 on plans by Jacques Mellet
