Among the precious medieval and Renaissance manuscripts on display at the Bibliothèque Humaniste, founded in 1452 and installed in the former Halle aux Blés, are a 7th-century lectionary and a 12th-century Book of Miracles. There's also a town register from 1521, with the first-ever recorded reference to a Christmas tree.
