Room 234-00

Filch's Office
Location information
Location	Ground Floor, Hogwarts Castle, Scotland, Great Britain
Permanent residents	Argus Filch Mrs. Norris
Affiliation	Hogwarts School

Room 234-00 is the room where Argus Filch lives in Hogwarts Castle. It is connected to the Entrance Hall, in the Ground Floor of Hogwarts Castle. It's a small, simple room with a single oil lamp hanging from the ceiling. It smells vaguely of fried fish. There are filing cabinets in it with details of the misdeeds of Hogwarts Students. Fred and George Weasley have an entire drawer to their own misdeeds. One of those cabinets are full of confiscated magic items marked "Confiscated and Highly Dangerous", in which Fred and George found the Marauder's Map. Filch keeps his chains and manacles in this office (it's common knowledge that he always begged Dumbledore to allow him to hang students by their ankles as punishment), and keeps them well polished.

Due to the office being owned by Filch, who is disliked by every student in Hogwarts, the students tend to avoid it at all costs. Harry, during his second year, was called in for punishment after tracking mud into the castle, and found a Kwikspell letter in this office, which eventually lead to him finding out Filch was a Squib.

• The office location is not mentioned in any of the films, but given its location in the books, it can be located in the circular building adjacent to the Entrance Hall. Alternatively, this building might house another rooms (such as Classroom 11 or the Staffroom). It is also possible that in the filmverse, Filch's office is located elsewhere in the castle.
• In Harry Potter Film Wizardry, Mr. Filch's room is mentioned as "Room 234-00". However, unlike in the novels, its location is given as in the seventh-floor.
