Casterly Rock, the seat of the Lord of Casterly Rock.

"It is mine, by right."
Tyrion Lannister expresses his rights to his ancestral home.[src]

The Lord of Casterly Rock is the ruler of the stronghold of Casterly Rock, the administrative center of the Westerlands. The holder is the ruler of the entire region of the Westerlands.

The Westerlands were originally a sovereign nation known as the Kingdom of the Rock, until Aegon the Conqueror arrived in Westeros and united the Seven Kingdoms. House Lannister, the richest family in the Seven Kingdoms, have ruled as the Lords of Casterly Rock for thousands of years. According to legend, they have held the title since the Age of Heroes, when Lann the Clever swindled House Casterly out of Casterly Rock using nothing but his wits.

Tyrion Lannister is Lord of Casterly Rock, inheriting the claim from his father Tywin Lannister and officially inheriting the title from his sister Cersei Lannister. Typically, the Lord of Casterly Rock also holds the title of Warden of the West.


Season 3

Although Tyrion is by right the heir to Casterly Rock, since his elder brother Jaime is a knight of the Kingsguard, Tywin makes it clear that he has no intention of allowing Tyrion to be the Lord of Casterly Rock. It is therefore not clear who the heir to Casterly Rock currently is.[1]

Season 4

With the murder of Tywin, Queen Cersei stands as the new Lady of Casterly Rock as Tywin's closest lawful heir, since Tyrion has been declared guilty of regicide and fled across the Narrow Sea. Although Jaime made a deal with Tywin to leave the Kingsguard and become his heir again, Tyrion's guilty verdict rendered that deal null, even if Tywin had lived.[2][3]

Season 6

With Jaime's dismissal from the Kingsguard,[4] it was possible that he would inherit his father's titles and positions, thus becoming the new Lord of the Rock ahead of his sister Cersei, but that never happened. 

Season 8

Cersei and Jaime are both crushed by rubble under the Red Keep during the Battle of King's Landing, leaving Tyrion to become the undisputed Lord of Casterly Rock after Daenerys Targaryen's victory.
