Prydonian Academy

The Prydonian Academy was an educational institution on Gallifrey. It was situated near Mount Cadon on Gallifrey. As Lord President, the Doctor] was able to access its so-called "black collection" and steal a portable temporal link. (PROSE: Timewyrm: Revelation)

Behind the scenes
Since "the Academy" typically means the "Time Lord Academy" in works like Interference - Book One and the Gallifrey audio series, and since Paul Cornell barely mentioned the place in Revelation, it's unclear whether the Prydonian Academy is a formal name for the Time Lord Academy, a part of a larger whole, or, indeed, what exactly it is.
