===The Westerlands===
The Westerlands are the Westerosi lands to the west of the Riverlands and north of the Reach. They are ruled by House Lannister of Casterly Rock, formerly Kings of the Rock. People of this region are often called "Westermen." Lannisport, lying hard by Casterly Rock, is the chief town of the region and one of the great ports and cities of Westeros. The Westerlands are rich in precious metals, mostly gold, which is the source of their wealth.<ref>{{Cite web|date=2019-10-05|title=Game Of Thrones: 10 Great Houses Ranked From Poorest To Richest (And How Much They're Worth)|url=https://screenrant.com/game-of-thrones-great-houses-worth/|access-date=2020-11-05|website=ScreenRant|language=en-US}}</ref> Keeping with Westerosi customs to give bastards a surname showing their origins,{{sfn|''A Game of Thrones''|loc=Catelyn VI, p. 369}} illegitimate children born in the Westerlands are given the surname Hill.{{sfn|''A Storm of Swords''|loc=Prologue, p. 12}}

====Casterly Rock====

A stronghold carved from a mountain overlooking the harbor city of Lannisport and the sea beyond, Casterly Rock is the ancestral seat of [[House Lannister]]. According to popular legend, the hero known as Lann the Clever tricked the Casterlys into giving up the Rock, and took it for himself. The Rock is renowned as the wealthiest region due to its abundance of gold deposits, and it is one of the strongest castles of the Seven Kingdoms as it's a completely hollowed out mountain taller than even the Wall. It has never been taken in battle, despite attacks by the Iron Islanders and the plans of Robb Stark in the War of the Five Kings. It was held by Lord [[Tywin Lannister]] before the [[War of the Five Kings]], but after his death, Queen Regent [[Cersei Lannister]] made one of her cousins [[castellan]] of the castle. As of ''[[A Dance with Dragons]]'', the narrative has not actually taken place in Casterly Rock, yet descriptions of it have been offered by the Lannisters in the POV chapters.

West of Casterly Rock is the coastal city of Lannisport. A busy port under the governance of the Lannisters of Casterly Rock, Lannisport thrives as a protected and wealthy city. The city is also home to many lesser Lannisters and other distant cousins with similar surnames, such as Lannys.

George R. R. Martin stated on his blog that he drew inspiration for Casterly Rock from the [[Rock of Gibraltar]].<ref group=S name=grrm_blog_080529/>
