The Cloister Bell was an alarm bell located in the Cloister Room inside TARDISes.

The Cloister Bell was used in the most serious of emergencies, which saw either the TARDIS or its inhabitants in danger.

Its distinctive, sonorous, ringing sound resembled that of a large church bell. It could be answered by anyone inside the TARDIS. The Fourth Doctor told Adric that if he needed him, Adric could sound the Cloister Bell, indicating it could be manually activated. He claimed that the ringing of the bell heralded ‘wild catastrophes and a sudden calls to man the battle stations’. (Logopolis)

It had the physical appearance of a large, golden bell. (Four Dimensions, A Rose by Any Other Name)

Cloister Bells were located in the Cloisters of Gallifrey and could be heard all over the planet when sounding. (Hell Bent)


The TARDIS mistakenly believed it was being attacked by the Pus Creatures of Rakos as it materialised in Magnus Greel’s bunker. While the Fourth Doctor slept, Romana II apologised for the interruption that it had caused. (Under Reykjavik)

As a harbingerof the Fourth Doctor’s impending regeneration at the hands of the Master and as a warning of his actions nearly destroying the universe, the Cloister Bell sounded. (Logopolis)

During the Fifth Doctor’s veryearly life, the Cloister Bell rang as the TARDIS was travelling back in time to Event One. (Castrovalva)

Later, when an established time corridor, through which the TARDIS was travelling, began collapsing, the Cloister Bell also rang. (The Mutant Phase)

It sounded when the TARDIS was trapped in a Dalek time corridor, and under imminent threat of destruction. (Resurrection of the Daleks)

During the beginning of the Doctor’s life, The Masteropened the Eye of Harmony in an attempt to take The Doctor’s remaining regenerations. The Cloister Bell rang to signal the impending danger. (The TV Movie)

As the Tenth Doctor began to fly the TARDIS erratically and at ever-increasing speed, the TARDIS signalled danger by ringing the Cloister Bell. (Children in Need Special)

Also, when The Master cannibalised The Tenth Doctor’s TARDIS, turning it into a paradox machine, the bell sounded as well. (The Sound of Drums)

When the Tenth Doctor and Fifth Doctor’s TARDISes crashed and merged together, the TARDIS rang the Cloister Bell. (Time Crash)

The TARDIS also used it as a warning of rhe impending “end of the universe”. (Turn Left)

During his travels alone and following the destruction of Bowie Base One, the Tenth Doctor heard the Cloister Bell inside the TARDIS as his own demise loomed, this led to the projection of Ood Sigma as a warning of his inevitable fate (The Waters of Mars) and was also heard when the TARDIS chicks appeared in the TARDIS. (Terror in the TARDIS)

The Cloister Bell sounded when the TARDIS, in a weakened state, fell into the path of an oncoming train. (Flatline)

Whilst in a dream-like reality, Clara threw a TARDIS key into an active volcano. As the key was melting, the TARDIS Cloister Bell was heard. (Dark Water)

The Cloister Bell rang right before the Eleventh Doctor, Alice Obiefune, John Jones, and ARC crashed and were separated in four dimensions. (Four Dimensions)
