Charms is a very popular class at Hogwarts. Known for the fun and useful spells learned here, students tend to think of it as an informal subject, there is always lots of fun to be had, especially with spells such as 'Tickling Charms'. The room is bright and lined with stages of stacked desks, with a large space on the floor for more space-consuming Charms and a teacher's desk underneath the large window which looks down upon the green lawns.

Muggle Studies is the study of muggles. Go figure. Compulsory for the first two years of school it is important that all wizards and witches have a good grasp of muggle life. It is, of course, easier for muggle borns.

The Trophy room is filled with all the awards students have, and can win throughout their school careers. Rows of cases of medals, trophies and shields line the room, light glinting technicoloured sparks around the room as it comes in the large window.

The Armour Gallery is a smallish room stuffed full of Suits of Armour. Once you enter, you are literally surrounded by these things. Creepy to some people, but a great place for playing hide and seek, or discussing something private, everything in here is always covered by a layer of thick dust, so those who enter usually have to brush their clothes if they bash against something.

Most of the Suits are old and rusty, some with odd arms and legs missing, as they were never restored after the Great Battle. Chameleon Ghouls often inhabit this room, as it offers a great opportunity to cause trouble.
