The third-floor corridor is a passage in Hogwarts Castle. It is also called the forbidden corridor when Fluffy was stationed there protecting the entrance to the underground chambers, where the Philosopher's Stone was kept.

About

The corridor is adjacent to these corridors and rooms which are also on the third floor:

An unknown third floor corridor has a statue of a one-eyed witch which leads to a secret passageway under the school to Honeydukes in Hogsmeade.

History

Professor Dumbledore put the Philosopher's Stone to Hogwarts School of Witchcraft and Wizardry to keep it safe. It was put in the underground chambers that are accessed through a trapdoor in a corridor of the third-floor. He used Fluffy to guard the trapdoor. The corridor was entered through a door that was locked. It could be unlocked using the Unlocking Charm. He told students at the Start-of-Term Feast that the corridor was forbidden to enter unless they wished to die a painful death.

Two years later, the third-floor was searched when Sirius Black destroyed the portrait of the Fat Lady. In December, Harry wanted to use a hidden passageway behind the statue of the one-eyed witch to go to Hogsmeade. He found it using the Marauder's Map. He had to tap it and use the password "Dissendium" to open the entrance.
