Dedicated to Our Lady of Mercy, the chapel was restored in 1630 and was used and maintained by the “venerable confraternity” which “assembled every Sunday and Bank Holiday to sing the office of Mary”. The confraternity, made up of lay people united in the aim of mutual assistance, also played another original role here: the Mont Granatique collectors were named as members of it. This stock of seeds was bought in the autumn thanks to legacies from private individuals, conserved in the barn located above the chapel and then handed out in the form of virtually interest-free loans.
The chapel was abandoned for a long time after the confraternity came to an end, but today it has heritage status. It has a larch shingle roof, a trompe-l'oeil facade which was restored by Guy Ceppa in 1984 on which there is a sundial with the motto “soli honor et Gloria” (honour and glory to God alone).
