The Stone Gargoyle is located in an empty corridor and to many students it isn't very significant although it is the entrance to the Headmaster/Headmistress' office. When given the proper password, the gargoyle will leap aside, and the wall behind it will split in two to reveal a spiral stone staircase that moves like a muggle escalator which visitors ride that moves slowly upward as the gargoyle's entrance closes behind them. The staircase leads to a highly polished oak door with a brass knocker in the shape of a griffin. The door is not sound-proof; a visitor standing on the staircase can hear anyone speaking in the room inside, although not necessarily distinctly unless the speakers' voices are raised. The oak door opens into a large and beautiful circular room with windows, at least one of which faces east with a view of some of the mountains surrounding the castle. The windows also afford a view of the Quidditch pitch. The walls of the office are covered with portraits of previous Headmasters and Headmistresses.
