King's Landing is the royal capital of Westeros and the Seven Kingdoms. King's Landing has an estimated population of 1 million people, making it the most populous city in Westeros. It is situated on the Blackwater river on the spot where Aegon the Conqueror landed in Westeros to begin his conquest. The main city is surrounded by a wall, which is manned by the City Watch of King's Landing, which is nicknamed the gold cloaks, after the cloaks they wear. Within the walls, the city's natural landscape is dominated by three hills, named after Aegon and his two sister-wives Rhaenys and Visenya. Poorer smallfolk (commoners) build shanty settlements outside the city. King's Landing is described as extremely populous but unsightly and dirty. The stench of the city's waste can be smelled far beyond its walls.
The royal castle, called the Red Keep, sits on Aegon's Hill. It is the seat of the royal court. The Keep holds the Iron Throne. Aegon commissioned the throne's construction from the swords of his defeated enemies. According to legend, he kept the blades sharp because he believed that no ruler should ever sit comfortably. Centuries later, kings still cut themselves on the throne. It is a common belief that one who cuts himself on the throne has been "rejected" by the throne and is therefore not fit to rule.
The city also holds the Great Sept of Baelor, where the Most Devout convene with the High Septon. It is the holiest sept of the Seven. The slums of King's Landing are called Flea Bottom, where residents are so poor they regularly subsist on "bowls of brown", a mystery stew that can include the meat of puppies and murder victims.
