In the upper part of the village of Bousson, one comes across a particularly mysterious building, the House of Tombstones. After lengthy restoration and enhancement work, the new museum site was inaugurated on Saturday 2 January 2016. The origin of the building, its various construction phases, its function and, above all, who inhabited it and gradually endowed it with its sculptural decorations are, for the time being, a mystery: in fact, despite the research carried out in a wide variety of contexts, nothing has emerged about this building, even if the total absence of information in the ecclesiastical archives of Valsusini at least proves that the building was never officially used for Catholic worship. To the west is the wall that gives the monument its name, which is also the best-preserved original structure of the entire house. As many as ten tombstones are embedded in this wall, decorated with geometric, religious and plant symbols that soften the frames. Three other tombstones, devoid of decoration, are walled outside the apsidal body and east, while two others are located inside the building. On all the tombstones are engraved phrases exhorting a life of penance and asceticism, in cultured French that can be dated between the end of the 17th and the first two decades of the 18th century. These hymns to penance and quotations attributed to saints and ascetics are a singular testimony to the multifaceted local religiosity of the 18th century, which was emerging from a serious crisis due to the struggles against the Waldensians and Huguenots. During the second half of the 17th century, these struggles left a heavy mark on the area, which was repeatedly devastated and plundered during Protestant raids. The general tone of Bousson’s gravestones has recently made it possible to link the culture that produced them to Jansenism, a current of Reformed Roman Catholicism that, by attempting to mediate with the Protestants’ religious positions, ended up being united with them and condemned. The museum is divided into two rooms, one of which is dedicated to the permanent exhibition of gravestones, the other periodically hosts temporary exhibitions on popular culture.
