The Defense Against the Dark Arts classroom is where students learn about defense against the dark arts, obviously. The classroom is one of the larger classrooms, and is usually decorated to suit the professor's taste. Though, lately all sorts of interesting artifacts and animal bones have been stored inside the classroom too, for students to look at. There is also a bookcase in the back for students to borrow books. And if some curious students look close enough, they might find a book or two on the Dark Arts itself, accidentally misplaced from the Restricted Section of the Library.

The Charms classroom is a unique classroom in the sense that it's seating is similar to that of a small ampitheatre, seating about forty students in a semi-circle sloping upwards with the professor standing on a small stage in the center. No one really knows why it's built like this, those some suspect that it's because of the former Professor Flitwick's height and him being tired of having to stand on books to be seen. The Charm's classroom is not only popular for students to come on their free time to practice their wandwork, but those who love theater come here from time to time to pretend they are acting for an audience without people sniggering behind their backs.

The Trophy Room is a room where distinguished awards that students and staff have received throughout the years are stored. From plaques to trophies to statues and shields, every award is displayed with love and care. A complete list of all Head Boys and Girls throughout the years is listed on an enchanted scroll that hangs on the back wall. Cleaning the Trophy Room with a toothbrush is a popular detention method that professors like to give to troubling students. The Trophy room is also where students with prominent parents or ancestors like to go and show off their family's glory. This area is currently unfinished due to the mending that must be done to refurnish the broken items from the war.

You know those suits of armors that sing Christmas carols during the holidays? Or the armors that bow, salute, whistle songs and such as students pass by? Well, the armory is where those armors go to be polished, cleaned, waxed or replaced. It is also where students like to go when they are being chased by prefects when caught out late at night. It's a simple process of finding the fattest suit of armor and hiding inside it until the prefect decides to give up. Now, getting out of the armor once the prefect gives up is a whole different matter.
