This chamber is long and rectangular, lit by low-hanging lamps. It contains a tank of encephala, or brains, that swim in a green solution. These particular brains are highly aggressive and will attack and constrict anything that tries to touch them or pick them up. The tendrils that the brains possess are implied to be physical manifestations of thoughts. The concept of thought and all related subjects are studied in this chamber.

This large, square room somewhat resembles Courtroom Ten of the Wizengamot. It is dimly lit, with stone tiers leading down to a pit in the centre. In this pit is a dais, upon which stands a very old stone archway with a tattered black curtain hanging from it. This arch separates the worlds of the living and the dead.

Records of prophecies are stored in this long, cold chamber with high ceilings and towering shelves lit with blue-flame candles. These prophecies, held in glass orbs, are magically protected, so that the only people who can lift them off their stand are the Keeper of the Hall of Prophecies and the subject or subjects of the individual prophecy. Anyone else who attempts to inspect the orb with their hands will be afflicted with instant madness.

The Love Chamber is a room behind a door that remains locked at all times and which cannot be unlocked by Alohomora or magical unlocking penknives. Behind the door is the most mysterious subject of study of the department, and the most powerful force ever to exist in the universe — which is known as "Love". It may also be used in attempts to understand and duplicate the magical protection self-sacrificing love creates, the only magic strong enough to repel the Killing Curse. There is said to be a large fountain of Amortentia in the room.

This is a dark room full of planets floating in mid-air. Presumably, it is from this Chamber where Wizards study the aspect of space, as it is one of the limits of magic (along with time). Visitors may find themselves floating as well.
