Hogwarts Third-Floor Corridor

The third-floor corridor was a passage on the third-floor of Hogwarts Castle, which could be accessed from the Charms corridor and the Grand Staircase.
==History==
The third-floor corridor was out-of-bounds during the 1991–1992 school year due to the entrance to the Underground Chambers, in which the Philosopher's Stone was hidden, being there, guarded by Fluffy. The door between the Charms corridor and the third-floor corridor was locked, although the Grand Staircase entrance was not, at least for a time.On the first day of term, Harry Potter and Ron Weasley got lost and attempted to force their way into the third-floor corridor, not realising which corridor it was. Argus Filch spotted them and accused them of knowingly attempting to trespass, but Quirinus Quirrell, who was nearby, had him leave them alone."Even worse than Peeves, if that was possible, was the caretaker, Argus Filch. Harry and Ron managed to get on the wrong side of him on their very first morning. Filch found them trying to force their way through a door that unluckily turned out to be the entrance to the out-of-bounds corridor on the third floor. He wouldn't believe they were lost, was sure they were trying to break into it on purpose, and was threatening to lock them in the dungeons when they were rescued by Professor Quirrell, who was passing." () Some weeks later, Harry, Ron and Hermione Granger hid in the corridor (after Hermione unlocked the entrance on the Charms corridor) from Argus Filch, but quickly left upon seeing Fluffy.
On Hallowe'en, Quirrell attempted to enter the Underground Chambers from the corridor, but was prevented from doing so by Severus Snape, who was bitten in the process.Quirinus Quirrell: Unfortunately, while everyone else was running around looking for it, Snape, who already suspected me, went straight to the third floor to head me off - and not only did my troll fail to beat you to death, that three-headed dog didn't even manage to bite Snape's leg off properly. () When Quirrell finally succeeded in passing through the trap door, Harry, Ron and Hermione went after him, with Dumbledore eventually following suit.Hermione Granger: I brought Ron round -that took a while - and we were dashing up to the owlery to contact Dumbledore when we met him in the entrance hall - he already knew - he just said, 'Harry's gone after him, hasn't he?' and hurtled off to the third floor.
