Following the recent move of this summer 2022, two-thirds of the heritage collections of the Heure joyeuse collection are now nestled in the heart of the building, in basements specifically dug during the architectural project.
We invite you to visit these conservation shops, usually inaccessible to the general public, and to discover some treasures. It will also be an opportunity to discuss with librarians the notions of preventive conservation and heritage value of works, within the framework of the national theme of this edition of the European Heritage Days, "sustainable heritage".
Free access from 1 pm to 6 pm, on Saturdays and Sundays, in the reading room of the heritage collection: a selection of remarkable heritage documents and treasures from our collection presented by librarians.
