Professor Umbridge's Office
This is Professor Umbridge's old office. A long time ago, the office of a certain Dolores Umbridge sat at the end of this corridor. Sensitive students can still catch a hint, a sniff of pink in the air. Now, it has nothing but dust and cobwebs. Legend has it that Harry Potter stood up to her and caused her to be dragged away from the castle.
The Dance Hall
Take the stairs to the Dance Hall to practise dancing or to talk with friends.
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, the Philosopher's Stone was hidden on this floor, and that was why it had been declared off limits that year.
