This magnificent building dating from the mid 18C was constructed at the request of Monseigneur d'Inguimbert (1683-1757). It features an apothecary and a mediatheque, and from late 2021/early 2022 it will house his collection of old books as well as scientific objects, medals, coins, paintings etc which have been donated to this library-museum. Reconstructions of the studies of d'Inguimbert and Casimir François Henri Barjavel (1803-1868), another of the town's benefactors, will complete the project.
