"The raven arrived from the Citadel this morning, Your Grace. The Conclave has met, considered reports from maesters all over the Seven Kingdoms, and declared this great summer done at last. The longest summer in living memory."
Grand Maester Pycelle to Cersei Lannister[src]

The Citadel is the headquarters of the Order of Maesters, scholars who advise the lords of the Seven Kingdoms on matters scientific, medical, and historical.

The Citadel was founded many centuries ago to promote and increase learning and knowledge in Westeros. It is administered by the Conclave, the ruling council of archmaesters. The Citadel is also where young men from the entire continent are trained to become Maesters.


Season 1

At Castle Black, Maester Aemon notes to Tyrion Lannister that the current summer has lasted nine years, and that reports from the Citadel say the days are growing shorter, indicating that its end is soon at hand.[1] When Aemon later reveals his past to Jon Snow, the surprised Jon says "You're Aemon Targaryen!". However, Aemon corrects him by stating that he is "a Maester of the Citadel, bound in service to Castle Black and the Night's Watch", stressing to Jon that a sworn brother of the Night's Watch abandons all previous family ties.[2]

Season 2

A special white messenger-raven arrives at the Red Keep in King's Landing from the Citadel. Grand Maester Pycelle presents it before Queen Regent Cersei Lannister and the Small Council, explaining that it signifies that the conclave of the Citadel has met, considered reports from Maesters all over the Seven Kingdoms and officially declared the ten year long summer to have finally ended, and autumn has arrived in Westeros.[3]

After the Fall of Winterfell, Theon Greyjoy convinces Maester Luwin to obey him by pointing out he is a Maester of the Citadel sworn to serve the Lord of Winterfell, a title that now belongs to him, as he has forced Bran Stark to claim publicly.[4]

Season 3

When Jaime Lannister is being treated by Qyburn at Harrenhal after losing his hand, he notes that Qyburn is not a maester, as he isn't wearing a maester's chain of office. Qyburn explains that the Citadel stripped him of his chain, expelling him from the Order of Maesters, because they found some of his experiments "too bold".[5] Later, Roose Bolton points out to Jaime that by treating him and accompanying him back to King's Landing Qyburn hopes Tywin Lannister will reward him by forcing the Citadel to give him back his chain. During their journey to the capital, Jaime asks Qyburn why exactly the Citadel took his chains, and Qyburn explains he experimented on living men, as "the only way to treat disease is to understand disease, and the only way to understand it is to study the afflicted."[6]

Season 4

When Cersei Lannister recommends the services of Qyburn to a young Lady, Grand Maester Pycelle is infuriated, as he believes Qyburn brought shame on the Citadel with his experiments.[7]

After the poisoning of King Joffrey, Tywin questions Oberyn Martell about the assassination, as it is well known that he hates the Lannisters and he studied poisons at the Citadel.[8]

In the trial by combat championed by Ser Gregor Clegane and Oberyn Martell, the former for the Crown and the latter for the accused Tyrion Lannister, Oberyn dies but he first poisons Clegane grievously with his spear, which was coated with Manticore venom. Cersei Lannister calls for Grand Maester Pycelle and Qyburn and, though the Grand Maester insists there is nothing to be done for him, Qyburn claims he can save Clegane. Pycelle protests, as Qyburn is not even a Maester, to which Qyburn replies that is for the best, as no maester knows how to save him. Pycelle exclaims that is the kind of arrogance that had him expelled from the Citadel, which considered Qyburn's experiments dangerous and unnatural, an opinion with which he agrees.[9]

Season 5

Cersei Lannister appoints Qyburn the new Master of Whisperers in the name of King Tommen, a decision Grand Maester Pycelle finds bewildering, as he is considered an embarassment to the Citadel.[10]

Samwell Tarly explains to Gilly that the Citadel, which harbors the largest library in the world, is located in Oldtown and it's where the maesters are trained. He then tells her about his wish to go to the Citadel and train to become a Maester before he was sent to the Night’s Watch.[11]

Maester Aemon dies of old age and Sam eulogizes him as a "maester of the Citadel, chained and sworn, and sworn brother of the Night's Watch, ever faithful."[12]

After Jon returns from Hardhome, Sam tells him that he wants to go to Oldtown to train at the Citadel to be a maester, so he can return and take the deceased Aemon's place as maester of Castle Black. He also wants to take Gilly and her young son with him, explaining that if they stay here they will be among the first to die in the coming war against the White Walkers. Jon agrees and Sam gravely promises to return, before leaving Castle Black with Gilly and her son on a cart, beginning the long journey to the Citadel in Oldtown.[13]

Season 6

Sam in tower library

Sam enters the citadel's library in awe.

Samwell and Gilly arrive at the Citadel. They enter a spacious chamber and Sam speaks to a maester seated at a large counter, writing. The maester listens to Sam's introduction and reads a letter written by Jon Snow while he was Lord Commander of the Night's Watch and checks his records, which still list Jeor Mormont as Lord Commander and Aemon as maester. He tells Sam that he'll have to speak with an Archmaester and can wait in the library. He bars Gilly from joining Sam by sharply stating that no women or children are permitted. He then leads Sam into the extraordinary library, which stretches above and below for a number of floors, leaving an amazed Sam to gaze at all the levels and books.[14]

Season 7

Sam begins to fall into a pattern of servitude at the Citadel, under the tutorial of Archmaester Ebrose, but keeps more vigorously occupied with the healing of greyscale of Jorah Mormont and the discovery of dragonglass on Dragonstone island.[15][16][17]

Reading through several of the books Samwell retrieves, Gilly is intrigued by various obscure bits of knowledge. She remarks on one page which records that the Citadel has 15,782 steps in it.[18]

Season 8

Samwell, feeling guilty, tells Daenerys and Jorah Mormont that he "borrowed" some books from the Citadel and asks forgiveness for his crimes.[19]

In the books

In the A Song of Ice and Fire novels, the Citadel is described as a university-like complex of buildings extending along both banks of the River Honeywine in Oldtown, linked by graceful bridges. The Isle of Ravens is the oldest part of the Citadel and the site of the ravenry, from where the maesters send messenger ravens out to all parts of the Seven Kingdoms. Other locations of note in the Citadel include the Seneschal's Court, Weeping Dock, and Scribe's Hearth.
