During Fifth Year, the Room of Requirement hosted the first meetings of Dumbledore’s Army. After one of the students hinted at this to Umbridge, the Inquisitorial Squad raided the room. Malfoy was among them, and he used his knowledge of the Room to his advantage the next year. It became his workshop. Malfoy provided a means of transportation into the castle that the wards couldn’t prevent, allowing Death Eaters to enter Hogwarts. The Room also served to hide Professor Trelawney’s sherry bottles, provided a place for Dobby to put Winky to sleep, and opened for Professor Dumbledore when he got lost looking for the toilet. The Hogwarts students willing to resist the Death Eaters at Hogwarts took refuge there and were supplied by Aberforth Dumbledore through a tunnel leading into his pub. The Room of Requirement also contained the diadem of Ravenclaw, one of Voldemort’s Horcruxes. Along with the rest of the room and Vincent Crabbe, the diadem was destroyed by Fiendfyre during the final battle.

Secrets and Spells

The Room of Requirement is my favorite example of Hogwarts’ magic. It responds to the needs and commands of its occupants, and does so with a sense of humor and certain irony. Tom Riddle hid a Horcrux there; having, apparently, some reason to believe that the maze of other objects inside it did not indicate that anyone else had ever found the room.

The entrance to the Gryffindor common room is guarded by a portrait of a “very fat woman in a pink silk dress”.



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.
