Library introduction: The library was designed by the master architect Sir Christopher Wren. There are four stone statues standing on the roof, representing the four oldest disciplines: theology, law, physics and math. The library is not very large, but has rich and precious collections, including rare books from the early 11th century, the first edition of "Principles of Nature" collected by Newton himself, manuscripts of Milton's poems, and A. A. Milne's "Winnie the Pooh" Pooh) manuscripts, etc., and a full-length jade statue of the famous romantic poet Byron, an alumnus, is also placed in a prominent position.
