Fire and paper do not go well together. The library, therefore, features a reduced number of torches on the walls to minimize any danger to the books. A number of large stained glass windows, placed at regular intervals where the room is part of the outside wall of the castle, ensure that sufficient light gets in. Stretching all the way to the ceiling, these windows depict different famous witches and wizards, momentous historical occasions, and beautifully detailed magical creatures.

Relax on one of the cushioned window seats. Watch the floor and nearby shelves change subtly in color as the sunlight shines through the stained glass panels. Read a book under the calm gaze of Merlin or the fearsome scowl of a Manticore. Sometimes, it is difficult to stay focused here, but there are students who swear that, when sitting at the window of Rowena Ravenclaw, work gets completed faster.

All rules apply here, and although the glass can't be broken by simple spells or physical force, please be careful and respect the artwork on the windows. Remember to keep your voice down so as not to disturb those also visiting the library.
