First-floor empty classroom (I)

There is an unused classroom on the first-floor corridor of Hogwarts Castle. It now seems to be used as a storage facility containing books, chairs, desks and several boxes.

Behind the scenes

 * There is a multiplication on the blackboard of this classroom. This seems to suggest Maths or any Maths-related magic (such as Arithmancy) was once taught in the classroom, but alternatively a student might have written the operation on the board (this is supported by the hat sketch and the doodles).

Appearances

 * Harry Potter and the Philosopher's Stone (video game)
 * Harry Potter and the Chamber of Secrets (video game)
