"He walked very fast along the corridor, the note to McGonagall clutched tight in his hand, and turning a corner walked slap into Peeves the Poltergeist, a wide-faced little man floating on his back in midair, juggling several inkwells."

The Serpentine Corridor[5] is a passage on the third-floor[1][2][3][4] of the Hogwarts Turris Magnus, connected to the courtyard corridor by a stairway[6] and the first-floor corridor by another.[7] Along the corridor are Classroom 3C,[5] Classroom 7A,[5] Lost Wands,[5] and the Ghoul Studies classroom.[5] Around the corner from Classroom 3C is a corridor where the staffroom sometimes exists.[8]


In the 1993-1994 school year, Remus Lupin took his third year class out of Classroom 3C and along the corridor, where he had a confrontation with Peeves. After using Waddiwasi to send him away, they left for the staffroom.[8]

Behind the scenes

  • This corridor can only be seen on the official Marauder's Map replica made by the Noble Collection.
  • Although the corridor's name is not present on the film, this is the corridor on which Harry sees Argus Filch's name on the Map, just before he sees Peter Pettigrew.
