Fourth Floor
Places of Interest
- The Library, particularly the Restricted Section
- Room containing the Mirror of Erised
- Mirror, behind which is a “roomy passageway”
Note: Except for the numbered areas of the library, numbers are added to indicate possible classrooms but those rooms are not further identified.
Events
Repeated nighttime visits to the Restricted Section tend to end with Harry dashing, unaware of where he’s going, down corridors and through doors. One of these escapes lead him to discover the Mirror of Erised.
Secrets and Spells
The Hogwarts Library is as dangerous as it is interesting. It contains, among other things, books that scream or bite. (See the floorplan for my list of subjects—these have no basis in the text.)
A large mirror on this floor hides a caved-in corridor.
Commentary
Notes
These maps takes the details from the books into account as well as the standard structure and architecture of castles. While not canon, this map is certainly one of the most well-researched and historically accurate blueprints of Hogwarts that anyone could create.
