Room 234-00 was the room where Argus Filch lived in Hogwarts Castle. It was connected to the Entrance Hall, on the ground floor of Hogwarts Castle.


Filch's Office

It was a small, simple room with a single oil lamp hanging from the ceiling. It smelled vaguely of fried fish. There were filing cabinets in it with details of the misdeeds of Hogwarts students. Fred and George Weasley had an entire drawer for their own misdeeds. One of those cabinets was full of confiscated magic items marked "Confiscated and Highly Dangerous", in which Fred and George found the Marauder's Map.[1] Filch kept his chains and manacles in this office (it was common knowledge that he always begged Dumbledore to allow him to hang students by their ankles as punishment), and kept them well polished.[2]


Due to the office being owned by Filch, who was disliked by every student in Hogwarts, the students tended 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 led to him finding out Filch was a Squib.[2]

Behind the scenes

"If found, please return this notebook to Mr Filch, Seventh floor, Room 234-00."

  • The office location is not mentioned in any of the films, but given its location in the books, it can be found in the circular building adjacent to the Entrance Hall. Alternatively, this building might house other 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 being on the seventh floor.
