Placed under the patronage of Saint Hilaire, this parish was given by Gannelon de Montigny, lord of the place, to the abbey of Marmoutier around 1042. Its reconstruction probably dates from this period; it then became a priory. The church has a rectangular nave ending in a choir with a flat chevet. An examination of the masonry easily reveals two distinct periods of construction: the Romanesque period and the Renaissance. Built of flint rubble with rendering, the western part of the building appears to date from the 11th or 12th century. A limestone cornice supported by rather crude corbels underlines the base of the roof. To the south, two narrow Romanesque windows flared inwards light the nave. To the north, the bays were later reworked and enlarged. On this same side, a Romanesque doorway was walled up; It allowed the church to connect with a building whose traces of detachment remain.
The bell tower was built to the north of the Romanesque nave, extending the western façade. The absence of a connection between the east and west walls of the bell tower and the north wall of the nave clearly indicates that it is an entirely later construction. However, its crowning is much later, as evidenced by its cornice, whose molding is in the classical style. Flanked by obliquely angled buttresses, it is covered with a saddleback roof.
The eastern half of the church appears to be an extension built during the Renaissance period. Its ogee-shaped cornice and the decoration of the eastern gable, as well as the moldings of the buttress bands, attest to this dating. A vast rectangular choir then appears to have replaced a semicircular Romanesque apse; the eastern gable and the southern and northern façades were then pierced with networked bays. In the lower part of the north façade, projecting ashlars appear to have supported the roof of a lean-to building. To the south, a sacristy was built in the 19th century.
Inside, the entire building is covered with a paneled vault with exposed tie beams and kingposts. The 18th-century high altar is surmounted by an Assumption of the Virgin inspired by Murillo's.
For the restoration of the roofs and façades, the Sauvegarde de l'Art Français (French National Art Protection Agency) awarded a grant of €30,490 in 2001.
