The Transfiguration Courtyard is one of the cloisters, in the inner part of Hogwarts Castle. This courtyard has grass in the open area, in which a big tree has grown over the centuries. There is one massive iron Armillary Sphere that stands in the center of the courtyard. The Transfiguration Courtyard has this name, because it is the location of the Transfiguration Classroom.
