Sketch of Hogwarts by J.K. Rowling

This annotated sketch by J.K. Rowling shows the layout of Hogwarts School of Witchcraft and Wizardry, complete with the giant squid that lives in the lake. In an accompanying note to her editor, J.K. Rowling stated, ‘This is the layout as I’ve always imagined it’. The positioning of various buildings and trees are all integral to the storylines of the Harry Potter books. Note how the author insists that the ‘Whomping Willow must stand out’.
