The parish church dedicated to Saint Anne, perhaps more anciently to the Virgin, depended on the diocese of Chartres. This former possession of Ganelon, treasurer of Saint-Martin de Tours in the 11th century, was undoubtedly part of the important donation made by his descendants Eudes and Rahier de Montigny for the benefit of the chapter of Chartres Cathedral around 1160.
This Romanesque building, 35 m long, with a single nave and flat apse, reinforced with buttresses and lit by round-arched windows splayed internally and simply chamfered towards the outside, was never vaulted in stone: it is covered with 'a paneled vault. The masonry is entirely made of Grison stone, including the frames, giving an austere appearance specific to this region of Perche.
We enter to the west through a semi-circular door with a double arch into the lower room of a bell tower-porch established later inside the original nave. The upper part of this bell tower was pierced with semi-circular bays. The eastern one was obstructed during the installation of the high roof of the nave and the bells were placed above in a belfry under a frame. The interior of the building was in fact covered as a whole by a paneled vault with molded beams and punches from the 16th century.
In the 17th century, the entire back of the choir was decorated with a large altarpiece with columns and pilasters, paintings and sculptures, of great decorative effect. A curious set of carpentry from the same period presents above a confessional a paneled pulpit surmounted by a large sounding board. Note in the furniture a carved Gothic canopy from the beginning of the Renaissance and on the glory beam a carved wooden calvary from the same period. The 19th century. added a gallery, repainted the vault and provided the windows with stained glass.
