 Inadequate preservation measures led to the loss of valuable books, manuscripts, and hand sketches, and soon the palace fell largely into disrepair.In the seventeenth century, Emperor Leopold I (1640–1705) had some of the most valuable holdings of the Ambras collections—mostly books and manuscripts—moved to Vienna, where they can still be seen at the Austrian National Library.In 1805, the remaining Ambras collections were threatened by the defeat of Austria by the French Empire.
