The Dungeon Cupboard is a small room in the Dungeon Corridor. It takes its name from its size and where it is located, in the Dungeons. It comprises an empty room filled with cobwebs, dust and some mice. Here, Rubeus Hagrid hid Aragog. The Acromantula was released by Tom Riddle's Cistem Aperio spell, and he rushed to the forest. This is also where Tom Riddle framed Hagrid, making him appear to be the one who unleashed the Basilisk.
