Capitol The Capitol ( also known as the Citadel ) was the home of the Time Lord s on Gallifrey . ( TV : " The Deadly Assassin " ) The Capitol was built on the remains of the original Capitol which was destroyed in the Gallifreyan Civil War . ( AUDIO : " Lies " ) The Capitol stood in the mountains of Solace and Solitude on the continent of Wild Endeavour . ( TV : " The Sound of Drums " ) It was enclosed in a " mighty glass dome " . ( TV : " Gridlock " ) It rested on a large , vertical beam , with a wheel - like structure securing it . ( TV : " The Name of the Doctor " , " The Day of the Doctor " ) The Panopticon was the main room of the Capitol , where the Eye of Harmony was secretly kept far below . ( TV : " The Deadly Assassin " ) The High Council met in the Capitol . There was a transmat system that linked the Council ' s room to the Death Zone . ( TV : " The Five Doctors " ) Also on Gallifrey was the Time Lord Academy . ( TV : " The Sound of Drums " ) The Towers of Canonicity and Likelihood lorded over the northern part of the Capitol . ( PROSE : " The Blue Angel " ) The Vaults were located underneath the Capitol . ( AUDIO : " Lies " ) The Vaults contained the ruins of the original Capitol , a graveyard for TARDISes ( PROSE : " Engines of War " ) and the Cloisters , which housed the Matrix and Cloister Bell s . ( TV : " Hell Bent " ) Surrounding the Vaults were ducts and serviceways dating from the Old Time . ( TV : " The Deadly Assassin " ) By the time of the Doctor , they were used by those who worshipped shrines dedicated to the cult of " Rassilon the Vampire " . ( PROSE : " Goth Opera " ) There was a repair shop in the Capitol ; among the items there were TARDIS es . Two technicians , Andro and Fabian , were working there when the First Doctor , with his granddaughter , stole a faulty Type 40 TARDIS . ( TV : " The Name of the Doctor " ) The Imperator offered Thessalia the role of chatelaine of the citadel . ( PROSE : " The Return of the King " ) The Capitol was " flooded " by Quark s in an invasion attempt by the Dominator s . The invaders were fought by Leela and K9 Mark I , who destroyed 39 between them . Though the invasion was thwarted , one of the Quarks was fitted with a bomb which damaged the Capitol heavily , necessitating the construction of a replacement building . ( AUDIO : " Time in Office " ) By the Last Great Time War , the Capitol had expansive but minimalist spaces with metal walkways , a darkened conference room , and a huge council chamber with Time Lords standing on suspended platforms . By the final day of the War , the Citadel was severely damaged by Dalek Saucer s . The crashed saucers remained on the surface next to the Citadel . ( TV : " The End of Time " ) Following the Fall of Arcadia , the Capitol became at risk with Dalek forces converging towards it . This danger was detected in the War Room of the Capitol , where the General drew up stratagems with his associates . The Time Vaults contained the Omega Arsenal , where , on the final day of the War , the Moment was stolen from by the War Doctor . ( TV : " The Day of the Doctor " ) After the end of the war , the Capitol was repaired . ( TV : " Heaven Sent " ) Layout . The Capitol was divided in eight " sectors " . Sector 1 ' s main tower housed the Panopticon , a vast hexagonal chamber in which great events of state were held . Elsewhere in the tower was the Capitol Museum , where the symbols of presidential office were on display , along with examples of every kind of robe of state , from the President and the Gold Usher to the Chapter Cardinals . Sector 2 was the political heart of the Capitol , housing an enormous assembly room for meetings of the full High Council , a conference room for the Inner Council and other small gatherings , and the President ' s office . Sector 3 was entirely dedicated to the Chancellor and the Chancellery Guard . Sector 4 contained the Castellan ' s office , the courtrooms , and the Security Compound , which itself comprised detention rooms , interrogation cells , and several execution rooms , most of which were officially disused . Sector 5 comprised hundreds of libraries , records rooms and archive stores . Sector 6 , which housed the various Chapters of the Time Lord Academy and the main force - field control area for the transduction barrier that shielded Gallifrey , was the largest structure in the Capitol after the Panopticon . Sector 7 was dominated by the Communications Tower , from which Space Traffic Control and Temporal Control monitored and logged every passing vessel in Gallifrey ' s vicinity . It was also rumoured to be the site of Gallifrey High Command ' s War Room , together with an extraction chamber — although the existence of such chambers was officially denied . Finally , Sector 8 was home to the Time Travel Capsule landing bays and an array of repair shop s . Below the repair shops was an area known as the TARDIS Graveyards , where TARDISes that reached the end of their lifespans were despatched . Somewhere in the citadel , a set of chambers were allocated to the Celestial Intervention Agency , but no one outside the Agency knew exactly where those chambers were . Deep beneath the Panopticon were the Panopticon Vaults , where the Eye of Harmony was kept . Deeper still were the Cloisters , the physical location of the Matrix , guarded by the Cloister Wraith s . Finally , buried near the very core of Gallifrey were the Time Vaults , where all the forbidden weapons of the Omega Arsenal were locked away . ( PROSE : " A Brief History of Time Lords " ) Behind the scenes . Though this was not directly contradicted or affirmed by the Graham Williams - produced TV story , the novelisation of " The Invasion of Time " describes the Capitol as covering " most of Gallifrey " and being surrounded by a sheer white wall . A dome was first associated with Gallifrey in the header art for " Doctor Who Magazine " s " Gallifrey Guardian " section ; this was later shown to be covering the Capitol in " DWM " comics like " The Tides of Time " , and Peter McKinstry used it when designing the Capitol for " The Sound of Drums " . " With the citadel it was an opportunity to take elements of the very organic TARDIS interior and apply them on a much grander scale , " he recalled . ( " ImageFX " magazine , October 2008 , p . 62 ) This image of the Capitol as a regular - sized city surrounded by a transparent dome was used in various episodes under showrunner s Russell T Davies and Steven Moffat , including a scene in " The Name of the Doctor " set before the First Doctor left Gallifrey .
