This office is the workplace and residence of the Divination professor. It is located up a small staircase from the Divination Classroom.

This is where Divination classes are taught at Hogwarts. It is located in the North Tower. It is accessible through a circular trapdoor and is described as looking like a cross between somebody's attic and an old-fashioned teashop.

The Arithmancy Classroom is where Arithmancy classes are taught. It includes number charts, a blackboard and large rows of tables for students to sit in.

The Room of Requirement is a secret room in Hogwarts that only appears when a person is in great need of it. The room then transforms itself into whatever the witch or wizard needs it to be at that moment.

The Ravenclaw Head's office is the thirteenth window from the right of the West Tower. The office contains portraits, a desk, and sleeping quarters. This was where Sirius Black was held captive, awaiting the Dementor's Kiss in 1993.
