Location from A Song of Ice and Fire by George R.R. Martin
The colossal Lannister stronghold carved into a seaside mountain, honeycombed with gold mines and halls of polished stone that proclaim wealth as a form of warfare.
Casterly Rock is less a fortress than a statement — the physical embodiment of Lannister philosophy that wealth is the truest form of power. The halls inside the Rock are vast and echoing, lit by a thousand candles reflected off gilded walls. Even the servants' quarters would shame a lesser lord's great hall. But the gold mines that funded this magnificence are running dry, a secret Tywin took to his grave and Cersei refuses to acknowledge. The Rock has never been taken by force, and the Lannisters consider it impregnable — which makes it a monument to the kind of pride that precedes a very specific kind of fall.
An enormous natural rock formation jutting above the Sunset Sea, three times the height of the Wall. The castle is carved into and around the Rock itself, its galleries and chambers descending deep into the earth where gold veins still glitter in torchlight. Lions adorn every gate and parapet in crimson and gold.
