This hall was located on the second floor of Hogwarts Castle. Inside, one could find several display cases, as well as a fireplace and a single portrait hiding a secret area with a chest. The room had high ceilings and windows, as well as a trio of smaller stained-glass windows on the rear wall. It could be accessed via a foyer in the second floor. The fireplace hid a secret shortcut used by Fred and George Weasley in 1991.
