Unused 4th floor classroom storage for the Mirror of Erised

"Erised stra ehru oyt ube cafru oyt on wohsi"
"I show not your face but your heart's desire"
-- Inscription on the Mirror of Erised (PS12)


"The Mirror will be moved to a new home tomorrow, Harry, and I ask you not to go looking for it again. If you ever do run across it, you will now be prepared. It does not do to dwell on dreams and forget to live, remember that."
-- Albus Dumbledore (PS12)

Unused 4th floor classroom storage for the Mirror of Erised

The unused 4th floor classroom contained stacks of chairs and desks and an upside-down wastebasket, but also the miraculous Mirror of Erised propped against a wall (PS12).


Harry discovered the room while running from Snape and Filch under the Invisibility Cloak after he was nearly caught prowling in the Restricted Section of the Hogwarts Library.

Harry was able to see his parents and a whole host of dead family members in the Mirror of Erised (PS12). When he brought Ron to the room, however, the other boy saw different things, including himself as Head Boy and Quidditch Captain holding the House Cup.

Dumbledore found Harry in the room and explained that the Mirror was not exactly “true” and only showed “the deepest, most desperate desire of our hearts.” He also said the Mirror was going to be moved to a safer place.

The mirror stands in front of the opening to one of seven passages out of the castle. However, the passage caved in sometime in the winter of 1992-1993 (PA10).



The room was evidently known to Fred and George, who used the passage behind the mirror to sneak out of the castle. Interestingly, the mirror itself seems to have been of little interest to the twins, who refer to it quite nonchalantly and as though it were a regular mirror (PA10). -BB

The passage leading from this room to Hogsmeade caved in during the winter of Harry's second year - about one year after Harry discovered the room and the mirror was removed (PA10). -BB
