Castamere is a ruined castle located south of the Crag and west of Ashemark in the northwestern westerlands; also nearby is Tarbeck Hall. The former seat of House Reyne, Castamere contains gold and silver mines.
Named after a nearby pool of blue water, Castamere began as a mine like Casterly Rock. After building curtain walls to guard the entrance with two stout towers, the Reynes constructed keeps and halls. As the gold and silver dried up, the mine below was widened and converted into halls, galleries, bedchambers, and a vast underground ballroom. While the surface fortifications resembled those of a minor lord or landed knight, nine-tenths of the castle was subterranean.
Kevan Lannister, the second son of Lord Tytos Lannister, served as first page and then squire to Robert Reyne, Lord of Castamere. Following the War of the Ninepenny Kings, tensions rose between the Reynes and Lannisters during the rule of Tytos. Castamere was where the opposing sides met to exchange hostages. Peace was short lived, however.
During the ensuing Reyne-Tarbeck rebellion, the Reynes retreated to Castamere after the destruction of Tarbeck Hall. With Roger wounded and many of their men killed in battle, the Red Lion's brother, Ser Reynard, abandoned the surface castle for the safety of the mine's oak-and-iron gate. Tytos's heir, Ser Tywin Lannister, ignored Reynard's offers and had his miners bury Castamere's entrances beneath stone. The Lannisters then dammed the pool's stream and diverted it into a mine entrance, flooding the underground chambers of Castamere and drowning those trapped inside. Tywin also had the surface buildings put to the torch. The fate of the Reynes and Castamere is remembered in the song "The Rains of Castamere".

Tyrion: The Crag is not so far from Tarbeck Hall and Castamere. You'd think the Westerlings might have ridden past and seen the lesson there.
Tyrion: Mayhaps they have. They are well aware of Castamere, I promise you.
