Marble Staircase

"[The Entrance Hall] housed a magnificent marble staircase that led to the upper floors."

- Description.

The Marble Staircase is a wide marble flight of steps in Hogwarts Castle that connects the Entrance Hall with the upper floors via the Grand Staircase.

Behind the scenes
Harry Potter and Lord Voldemort had a brief duel on the staircase, which Harry blocked several of Voldemort's Killing Curses.
 * In the films, and the first (PC version), second (PC version), third (PC version), fifth and sixth video games, the Marble Staircase appears to be made of rough stone, not marble. In all the other video games in which it makes an appearance, it closely resembles the book description.
 * In The Wizarding World of Harry Potter the Grand Staircase is referred to as the Marble Staircase.
 * In the early film adaptations (POA, GOF, OOTP and HBP) the staircase is viewed as a small flight of stairs leading to the Grand Staircase. Whereas in the last Harry Potter film, we can see a rather long passage of stairs leading into the upper floors.
