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.

According to biblical accounts, the apostle "Saint Jacques" was the first person to be executed for his faith, as recorded in the Acts of the Apostles, making him an early martyr (blood witness) of Christianity. His tomb in the town named after him, "Santiago de Compostela" (Galicia, Spain), is one of the most famous and important pilgrimage destinations in the world and is often ranked third after Jerusalem and Rome. Yesterday (July 25) was his feast day in the calendar of saints. When this date falls on a Sunday (this was last the case in 2021), the Catholic Church celebrates a special "Holy Year" there (extended by Pope Francis until 2022 due to the coronavirus pandemic).

Built on an old feudal motte, which is still visible and was completely destroyed during the Hundred Years' War, it was replaced in the second half of the 15th century by the castle, the remains of which can still be seen today. The Saint-François Tower remains as it was, with its Grisons base and rows of white stone. Halfway up the circle is the Cord of Saint Francis of Assisi, with its coils and knots. A Renaissance building was added in the 16th century, and new buildings were constructed in the 17th and 18th centuries.

Of course there is the castle but the rest of the village is really worth a stop (church, wash house, half-timbered house, etc.)

The cathedral is the seat of the bishop of the Roman Catholic diocese of Chartres
