Built in the second half of the 11th century, the church of St Blaise de Bonchamp presents itself in a first configuration of Romanesque style, traceable by its bedside located at the back. Two side chapels, decorated with altarpieces, were added to the nave (the first in 1639 and the second in 1731). The nave itself was enlarged during the 18th century. The rich interior decoration is inspired by the late Baroque style, the Louis XV era, which reached its peak during the parish ministry of Jacques-Alexandre Mesnard du Hallay, parish priest of Bonchamp from 1743 to 1773. A magnificent wrought iron pulpit dating from 1768 can be found here.
