Adjacent and to the left of the Trophy Room, the Armor Gallery is a long hall like room filled with old suits of armor. This is another one of Peeves' favorite place to play and annoy Argus Filch by knocking over the suits of armor and creating a loud ruckus.

The Hospital Wing is a testimony that rooms move and change over time in Hogwarts. Originally located on the first floor the Hospital Wing is now located on the third floor but nothing inside it has changed much. The entrance is sealed by large double Oak doors that swing out and the half circle room with long straight walls is lined with beds with white sheets and privacy screens. The far wall is made of windows over looking the grounds. There is a single door in this room and that leads to Madam Pomfrey's stores of medicinal potions, her office, and her living quarters. It is best not to upset or excite any of the patients here under Madam Pomfrey's watchful eye, she's not shy about throwing people out of the hospital wing.

Just because the professor of Charms and Head of Ravenclaw House, Filius Flitwick has to teach his class from the top of a pile of books does not take away from his skill and vast knowledge on the subject that he teaches. The room is set up ideally for dueling as it were. The door to enter the classroom is in the back and the desks are separated into three tiered juror type boxes that are on either wall. The center of the floor is left open for practical lessons and the very front of the room is where the chalkboards are, a wall of high windows over looking the grounds, and of course, Professor Flitwick's famous stack of books.
