According to tradition, the church choir covers the remains of an older building, possibly dating back to the 6th century, which was built to house the saint's body. According to current knowledge, the commune of Saint-Piat (Sanctus Piatus in Latin) officially appeared in 1087, mentioned in a charter of the Nottonville Priory (Eure-et-Loir), on which it depended. The current building was rebuilt during the time of Francis I, as suggested by the date 1535 engraved on two buttresses of the apse and the date 1542 engraved on a piece of wood from the vault. This is according to a study by the SAEL (Eure-et-Loir Archaeological Society). The three-sided apses, the dripstone towers (horizontal members projecting from a wall), and the sculpted roof structures are a testament to the importance of the reconstructions carried out in the department during the 16th century. The church of Saint-Piat is one of them. While the church has not been officially recognized, it nevertheless contains objects that have attracted attention both for their antiquity and quality, but not always for good reason. Their artistic value, far from attracting only religious or aesthetic interest, has also aroused a covetousness that, unfortunately, remains for some of them. Fortunately, those still in place are carefully cared for and offer the curious a story to discover, a beauty to slowly ponder as they progress toward the choir.

Mentioned in 1159 as a possession of the chapter of Chartres, the oldest parts of the church of Saint-Léger, the nave and western façade, must date back to the 11th century. The nave, 15 m long and 7 m wide, is built from small rubble stones embedded in mortar. Only the corner quoins of the façade and the semicircular arch of the entrance door are made of dressed stone. In 1514, a larger choir (10 m X 10 m) finished by a flat wall, was added to the east. Some of its pointed arched bays have retained their beautiful tracery. The entire choir and nave are covered by a beautiful framework in the shape of an inverted hull. A significant decoration, created in the 18th century, woodwork, stalls, work bench, glory arch, lectern, and communion railing have been fortunately preserved. Traces of medieval wall paintings and a coat of arms were spotted on the walls, as well as ancient graffiti on the exterior. A 12th-century stone baptismal font and a 15th-century stone statue of Saint Léger are listed as Historic Monuments. A slate bell tower, topped with a slate spire, rises above the slightly recessed gable of the western façade. The Sauvegarde de l'Art Français (French Art Protection Agency) granted aid of 100,000 francs in 1992 and then 40,000 francs in 1993 for essential work on the framework and roof.
