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.

The Church of Saint Sauveur La Trinité, probably built in the 12th century, is notable for its Romanesque windows with columns and capitals. On its walls, alternating with the consecration crosses, one can admire a Stations of the Cross in blue enamel on earthenware. The choir is lit by five Romanesque windows decorated with stained glass depicting Our Lord and the four Evangelists.

Saint Mames was martyred in Cappadocia around 1274: local legend has it that a saint offers a helping hand to cross the Loir. On April 17, 1707, thunder struck the bell tower.

The church consists of a single nave, extended by a single-bay choir, and a semicircular apse. Two canted chapels, forming a false transept, were added during this renovation. The church is dominated by a timber-framed bell tower that rises above the first bay of the nave. The gable of the western facade was rebuilt in the last century, an external wooden porch removed. The central axis of the current facade is punctuated by a semicircular door surmounted by an archivolt, a circular opening on the first level and a small window pierced in the upper part of the gable. On the north side, a highly raised stringcourse forming a cornice, resting on simple modillions, still survives in the upper part of the wall. Additional openings were added to the old, narrow, and uneven openings in the last century, in the nave, as well as in the choir and apse, to allow more daylight to enter the building. The interior of the church is covered with a paneled roof structure: the one covering the nave is believed to date from the 16th century. The entire structure has been given a coherent decoration, from the faux-stone plasterwork to the paneled vault, the furnishings, and the statuary. The church also boasts a 17th-century polychrome wooden statue of Saint Barbara. The Prunelé coat of arms appears at the bottom of the stained-glass window of Saint Louis and, outside, on a medallion on the apse wall. The Sauvegarde de l'Art Français (French National Art Protection Agency) granted €5,000 in grants in 2004 for masonry and roof repairs and the installation of drainage.

Porte de Boisville Its ogival portal opens into a thick quadrangular massif where there was a room for operating the portcullis. We can still see the groove in the thickness of the walls. On the left and right two small funnel-shaped spaces allowed the defenders to observe and repel the enemies who appeared on the bridge. The gate was topped by a building serving as a guardhouse which was demolished in 1761. The guarding of these doors and their keys was in the troubled times of the Hundred Years' War the subject of concern for the inhabitants and also a source of quarrels and trials between the city and the abbey. This gate is preceded by a bridge of 5 stone arches, the one adjoining the gate was built in 1774 and replaced a drawbridge which defended the entrance.

Bonneval, nicknamed the little Venice of Beauce

The chapel dedicated to the Virgin, erected at the beginning of the 16th century, was set on fire by lightning in 1878 and completely destroyed. Only the Gothic style western facade and its bell tower were consolidated and restored in 1887 in order to serve as a monumental portal to the adjoining Champdé cemetery. The large late flamboyant Gothic portal, at the center of a richly decorated facade, is composed of a large third-point arch and two twin basket-handle doors framed by flowered buttresses. The harmony of the proportions, the quality of the work and the refinement of the decorations make these remains a historical monument in their own right. The facade of the chapel is visible from the outside at the entrance to the Champdé cemetery.
