On this Sunday of the European Heritage Days, the public library of Lille opens its doors to you. In the company of the bmL heritage team, come and share a special moment around the heritage collections that it precisely preserves. Through an 1h30 route, your guides will welcome you in the garden of the library around a quiz. They will give you the history of the library and then take you to admire the richness of precious collections, periodicals, XIX-XX special collections, photographic, iconographic and musical collections. Finally, you will explore behind the scenes to the conservation stores. Manuscripts, incunables, daguerreotypes, thread labels, herbaria, artists' books... will have no secrets for you! Before leaving, a few reproductions of the heritage collections will be offered to you.
