North Tower

To enter the North Tower, it is necessary to climb a ladder on the seventh floor through a trapdoor in the ceiling. The North Tower contains Sybill Trelawney's residence and one of two Divination classrooms. This classroom is at the base of the North Tower and is a round room with walls lined with shelves (they hold teacups, crystal balls and decks of cards), small round tables, armchairs and pouffes. The classroom also has an oppressive fire with a copper kettle that gives off heavy fumes.
