"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."
— Description[src]

The Grand Staircase was a massive stairway in Hogwarts Castle, the structure was mainly used to access each floor of the castle, including the dungeons.[1] Rowena Ravenclaw was the Hogwarts founder who invented the concept of moving stairs.[2]


The ever changing staircases

There were hundreds of portraits covering the walls in this tower, some of which concealed secret passages to other areas within the school. The multiple staircases in the Grand Staircase led from platform to platform and went as high as the seventh floor where they came to an end. The stairs also had a knack for moving around the staircase chamber, usually when a student was walking up one of them. There were also many trick stairs that caused the victim to sink through a step and required another person to pull them out. However, it was second nature to most of the older students to jump them.[1]

  • The Fat Lady's portrait is on the seventh floor landing in the later films making it entirely visible to passers by; however, in the first film, her portrait is shown in a corridor somewhere else in the Castle.
  • In the third movie, it's shown that Grand Staircase travel upward to more than ten stories.
  • In the first two films the stairs are shown to have door to corridor at every landing. But in the next films, one floor is equal to two floors in the first two films.
