In the fall of 2024, Filigrane Archives was offered an exciting mandate by the MRC de d'Autray. The latter consisted of the processing funds of the Corporation du patrimoine de Berthier and that of an individual, Jacques Rainville. The two funds bear witness to the historical and heritage richness of Berthier and its territory on the one hand, and to the role that the Corporation and Jacques Rainville played in highlighting them to the public.
