History: The church of Castelnau must have fallen under the blows of the English during the Hundred Years' War, because the current church dates from the end of the 100th century. Work was being done on its reconstruction in 1545. It is an unfinished Gothic monument, the waiting stones are visible in front of the facade. A square tower, to the right of the church. The church door was fitted with a temporary arched doorway with a triangular pediment. The apse of the church is small because a larger space has been reserved for the faithful. Around the altar 2 statues: on the left Mary Magdalene with her vase of perfumes for embalming (patron of the parish) and on the right: the statue of the Sacred Heart.
