"There were a hundred and forty-two staircases at Hogwarts: wide, sweeping ones; narrow, rickety ones; some that led somewhere different on a Friday; some with a vanishing step halfway up that you had to remember to jump."
The Grand Staircase is a massive structure in Hogwarts Castle, mainly used to access each floor of the castle, including the dungeons. There are hundreds of Portraits covering the walls in this tower, some of which conceal secret passages to other areas within the school.

The multiple staircases in the Grand Staircase lead from platform to platform and go as high as the seventh floor where they come to an end. The stairs also have a knack for moving around the staircase chamber, usually when a student is walking up one of them. There are also many trick stairs that cause the victim to sink through a step and require another person to pull them out. However, it is second nature to most of the older students to jump them.


It was Rowena Ravenclaw who came up with the idea of using moving stairs.

In May of 1998 Severus Snape and Death Eaters Alecto and Amycus Carrow watched students as they marched from the Entrance Courtyard to the Grand Staircase.
