Founded in 1452, the Humanist Library’s stellar collection features a 7th-century book of Merovingian liturgy, a copy of Cosmographiae Introductio (printed in 1507), in which the New World was referred to as ‘America’ for the first time, and the first written mention of the Christmas tree (1521). At the time of writing the library was under renovation; it is set to reopen in all its glory in autumn 2016. For details, call or visit the ground floor info desk.
