"They slipped through the doorway behind them and down a tightly spiralling stone staircase. As they reached the bottom of it, they heard voices."

A tightly spiralling stone staircase leads up to the West Tower battlements. It is two staircases away from the Hospital Wing corridor, and was used by Harry Potter and Hermione Granger after rescuing Sirius Black from Filius Flitwick's office.[1]
