"Built in the neo-Gothic style, the chapel of the Suin, Randon, and de Salignac-Fénelon families was built in 1843. The crypt, whose entrance is to the right of the altar, contains the burial place of members of the Suin, Randon, and de Salignac-Fénelon families, owners of the Château d'Hermaville from 1819 to 1920.
Their epiraphes are engraved on marble plaques adorning the chapel walls. At the foot of the altar, a simple enamel plaque commemorates Marshal Randon (1795-1871), who was Governor General of Algeria, Marshal of France in 1856, and Minister of War under Napoleon III. His body is buried in Saint-Ismier, Isère.
The coat of arms of Jacques-Louis-César-Alexandre Randon appears on the stained-glass window of the church located above the porch, since he was the husband of Constance Suin (1811-1891), daughter of the owners of the Château."
