The Transfiguration Courtyard (also known as the Middle Courtyard) is one of the cloisters in the inner part of Hogwarts. This courtyard has an open grass area and a large tree. There is one massive Armillary Sphere that stands in the center of the courtyard. The Transfiguration Department is located somewhere off this courtyard (hence the name). Timothy the Timid's portrait is also to be found here. He may ask you to cover his portrait because someone is looking at him.
