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 mining resources, and it is one of the strongest castles of the Seven Kingdoms. 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.
