Dating from 1843, the Neo-Romanesque corn exchange has been equipped with brand new basements, a pink Vosges sandstone contemporary extension and a new esplanade. Entirely reworked, the edifice opened in 2018, and now does full justice to its precious holdings: nearly 450 manuscripts, 550 incunabula (books printed prior to 1500), and 2,000 printed works from the 16C. Among its treasures are the oldest book in Alsace, the 7C Sélestat Lectionary.
