At the request of the bishop Étienne Le Camus, the first stone of the church of Saint Louis was built between 1689 and 1699.
[1] Claude Mollard, a king's engineer and local architect, drew up the plans according to the classical French style.
The stained glass windows were produced by the master glass-maker Louis Balmet.
[4] Outside, a black marble plaque bears a Latin inscription which means: "Louis the Great erected this house for the Lord in the year 1699".
The interior of the church contains a figure of the Virgin Mary in white marble of the 16th century; paintings dated 1680 and the hand of a Dominican friar, Brother André; confessionals and a pulpit dating from the 17th century in walnut wood and an 18th-century altar.
