Former oratory, the chapel consists of a broken cradle choir of the thirteenth century on which was discovered a painted decoration of the eighteenth, released in 2008. Deposited, the central medallion of a brick vault built below, was restored in 2023. The nave and sacristy are from the seventeenth and nineteenth centuries. The ex-voto in thanks to the Virgin Mary, painted, embroidered or engraved on marble plates (1830-1967) are worthy of interest, especially the rare representations of boats before steam navigation.
