Third Floor Corridor

Third Floor Corridor
The third floor corridor is one of the many corridors in the Hogwarts Castle. It is located on the third floor on the side that the Grand Staircase side of Hogwarts is. You can access this corridor through the Grand Staircase or the Suspension Bridge Staircase.

Some say that a long time ago when Harry Potter was at Hogwarts that The Philosopher's Stone was hidden on this floor and that was why it had been off limits that year.
