Panopticon Vaults

The Panopticon Vaults were chambers located below the Panopticon, in the Time Lords' Capitol on Gallifrey. They housed the Eye of Harmony, which made time travel possible. (PROSE: A Brief History of Time Lords)

Here, the Eye was controlled by a crystal-shaped access system (TV: The Deadly Assassin) called the "Obelisk of Rassilon." (AUDIO: Renaissance) Most believed the existence of this vault was a myth. (TV: The Deadly Assassin)
