TARDIS gymnasium

From Tardis Wiki, the free Doctor Who reference

The Eighth Doctor showed the TARDIS gymnasium to Tamsin Drew during her three-hour tour of the TARDIS. It resembled a torture chamber. (AUDIO: Nevermore)

After climbing many pipes and ladders in the Bank of England, the Eleventh Doctor commented that he was "[g]oing to reactivate the TARDIS gymnasium after this", indicating that it was deactivated some time after Tamsin's adventures. (GAME: The Eternity Clock)
