TARDIS Graveyards

Below the repair shops of Gallifrey's Capitol was an area known as the TARDIS Graveyards, where TARDISes that reached the end of their lifespans were despatched. (PROSE: A Brief History of Time Lords)

The Doctor's TARDIS was once taken here to die when the War Doctor and Cinder were arrested for making their intentions to stop Rassilon destroying the Tantalus Eye public, but the Doctor took it away before any damage was done. (PROSE: Engines of War)
