In 'A Song of Ice and Fire', what is the name of the capital city of the Seven Kingdoms?

In A Song of Ice and Fire, the capital city of the Seven Kingdoms is King's Landing. Located on the eastern coast of Westeros, it sits on the Blackwater Rush and serves as the seat of the Iron Throne for much of the series.

Aegon the Conqueror founded King's Landing after landing there during his conquest of Westeros. The city grew around Aegon's hill, where he established the Red Keep, the royal castle. Other prominent landmarks include the Great Sept of Baelor and the city's defensive walls, known as the city walls.

King's Landing is frequently confused with Winterfell, Casterly Rock, or Highgarden, but those are regional strongholds and seats of powerful houses. The capital's political importance makes it the setting for court intrigue, succession struggles, riots, and battles throughout George R. R. Martin's novels. Its name also appears in the television adaptation Game of Thrones.
