The Room of Requirement is perhaps Hogwarts’ most mysterious room – changing to whatever the visitor needs it to be. Here’s every version of the room that we have ever discovered.

 

From the headquarters of Dumbledore’s Army to a chamber full of chamberpots, the Room of Requirement has had many makeovers over the Harry Potter books.

After all, depending on the needs (or bladder) of the passer-by, it can be just about anything. Well, within reason: according to Gamp’s Law of Elemental Transfiguration, it can’t produce food, as Ron pointed out. (Yes, really, Ron pointed this out once.)

Although we will never know the near endless possibilities of the Room of Requirement’s many forms, we can at the very least provide this handy interactive guide to every room we have seen it to be over the course of Harry’s Hogwarts’ days. Do you remember them all?
