Its construction was made possible by the then American ambassador, Jacob Gould Schurman, who organized a campaign in the United States to collect donations for this purpose. The only artful decoration it offers is a sculpture of Pallas Athene above the main entrance, with a caption penned by the scholar Friedrich Gundolf: “To the living spirit”. The courtyard of the New University holds the Witches’ Tower (Hexenturm), the only surviving and once strongest part of the town’s medieval fortifications.
