Castamere

Castamere is a castle located south of the Crag and west of Ashemark in the northwestern Westerlands; also nearby is Tarbeck Hall. The current seat of House Reyne, Castamere contains gold and silver mines.

Layout
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.

History
The rich veins of gold and silver allowed House Reyne to become nearly as wealthy as House Lannister of Casterly Rock during the Age of Heroes.

Rhaena Targaryen and her dragon, Dreamfyre, briefly stayed at Castamere with the Reynes in 51 AC. King Jaehaerys I Targaryen visited the castle in 55 AC.
