Serpentine Corridor

The Serpentine Corridor is a wide, curved corridor in the Hogwarts Turris Magnus at Hogwarts Castle. One can access the Defence Against the Dark Arts, the Ghoul Studies and Arithmancy Classrooms through this corridor, as well as Lost Wands.

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.
