Staircase between the ground-floor and second-floor corridor

"He crept along the corridor below, pushed aside a tapestry about halfway along, and proceeded down a narrower staircase, a shortcut that would take him down two floors."

- Narrative

The ground-floor and the second-floor corridor are connected by a narrow staircase hidden behind a pair of tapestries, with a suit of armour stood at the top. It has a trick step halfway up that most students remember to jump, and the staircase itself seems to be common knowledge. Gryffindors use it to shorten their route to Gryffindor Tower. Harry Potter used the staircase when heading to Severus Snape's office in 1996, but stepped on the trick step and dropped his golden egg, attracting Argus Filch, Snape and Bartemius Crouch Jr. (disguised as Alastor Moody.
