"A lopsided sign on the nearest cubicle read: Auror Headquarters"
-- inside the Department of Magical Law Enforcement (OP7)
A division of the Department of Magical Law Enforcement in the Ministry of Magic.
Located on Level Two of the Ministry of Magic Headquarters, Mr Weasley takes Harry Potter through the office before his trial. Auror Headquarters consists of a series of open cubicles, with each Auror being assigned a space to work. The cubicles are decorated with pictures of known Dark wizards, maps, clippings from the Daily Prophet, and other odds and ends. Kingsley Shacklebolt's cubicle is located at one end (OP7)
The description of the Auror Headquarters as "a cluttered open area divided into cubicles, which was buzzing with talk and laughter" impresses Harry, who is thinking about becoming an Auror when he leaves Hogwarts (OP7)
