The second floor girl’s toilet was the location of Hermione’s first Polyjuice-making. But that’s the least of the excitement the room has seen; Tom Riddle’s possessed diary changed hands there, Myrtle died there, and Mrs. Norris had an unpleasant encounter with the Basilisk. On the other side of the castle, Slughorn was accustomed to holding extravagant parties. Harry followed Draco and Snape out of one of these events, and overheard them arguing.
Secrets and Spells
To open the Chamber of Secrets, say “Open!” to the broken tap in Moaning Myrtle’s bathroom.
The size of Slughorn’s office makes Harry wonder whether the teacher had enlarged it to contain so many guests.
Near the Defense office is a staircase concealed by a tapestry. It provides an easy shortcut, which the students use to get to the Gryffindor tower. Unfortunately, it has a vanishing step that Neville never fails to forget.
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.
