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.

Church built in the first half of the 16th century, then raised in 1752. It is formed of a nave preceded by a narthex and adjoining two chapels forming a false transept. The 16th century door is formed of a low arch, adjoining smooth pilasters which support the lintel, above which a triangular pediment stands out from the wall. The church is decorated with murals in the apse and the side chapels, dating from the 16th and 17th centuries. In the choir, the paintings date back to the 19th century. Large flamboyant Gothic windows illuminate the building and retain stained glass windows.
