Casterly Rock

**Casterly Rock**, nicknamed the **Rock**, is a castle and the seat of House Lannister. The capital of the Westerlands, it is on the Ocean Road and overlooks the harbour of Lannisport and the Sunset Sea. Nearby strongholds include Kayce and Feastfires to the west, Sarsfield to the north, and Cornfield to the south.

## Layout

Casterly Rock is carved out of a colossal stone hill beside the Sunset Sea. It is popularly believed to resemble a lion in repose at sunset. According to George R. R. Martin, the Rock is two leagues (six miles) long from west to east and has a width of two miles from north to south. Its peak is about 2,100 feet high which makes it three times as high as the highest point of the Wall and taller than the Hightower of Oldtown too.

The Casterly's of antiquity built a ringfort on the peak, and as millennia have passed its natural defences have been expanded with walls, gates, and watchtowers. The base of the Rock contains large sea-carved caverns. The stone has been mined for thousands of years, so there are hundreds of mineshafts in the depths of the Rock, as well as yet untouched gold veins.

The face of the mount has windows and arrow slits scattered all over, they look small from the outside but it is only an illusion due to the huge size of the Rock. The entire stronghold—tunnels, dungeons, storerooms, barracks, halls, grand halls, stables, stairways, courtyards, balconies, gardens, a sept, passages, caves, mines, galleries, chutes, wells, barracks, armories, bedchambers, servant's quarters, etc.—lies within the Rock itself. The only exception being the watchtower on the top of the mount that is also used by the maesters as a rookery. According to George R. R. Martin, this particularity makes Casterly Rock the strongest and most impregnable seat in all of Westeros.

In the bowels of the Rock are rooms where caged lions were once kept, cells for the worst prisoners, as well as oubliettes so small that a man cannot even sit down in one.

The Lion's Mouth, the main entry to Casterly Rock, is an enormous natural cavern reaching two hundred feet high located on the south face of the Rock. It is accessible via a great stone stairway with steps wide enough for twenty riders. There are sea gates at the base of the west face, large enough for galleys and cogs to sail into the caverns under the stone, where the Lannisters have their own protected docks, as well as wharves, and shipyards. However, the bulk of the Lannister fleet anchors in the habour of Lannisport, the port city that lies close by to the south of the Rock. From below the Rock thunder can be heard, where the sea comes in.

The Golden Gallery contains treasures of the Lannister's, including gilded ornaments and walls. The Hall of Heroes is where the Lannister's and their close kin who have died valiantly are interred. The armour of Lannister's of old are also displayed in the hall. The Stone Garden is a godswood in a cave within the Rock. It contains a twisted weirwood, a tenth the size of Raventree Hall's, whose tangled roots have almost filled the cave, choking out all other growth.

## History

### House Casterly

The region was probably inhabited by children of the forest and giants before the arrival of the First Men, and numerous animals have made it their home as well.

Legend says that Casterly Rock is named for the family of First Men who ruled it in the Dawn Age and the Age of Heroes, the Casterly's. After their founder, Corlos, discovered gold within the Rock, the Casterlys fortified the entrance and carved halls and tunnels deep into the stone.

The Lannister's trace their rule over the Rock back to Lann the Clever, who tricked the Casterly's out of their castle and claimed it for his own. Some claim that Lann still haunts the fortress, which has never fallen.

### Kings of the Rock

The Kings of the Rock from House Lannister took their title from their seat, and members of the family founded nearby Lannisport. During the coming of the Andals to Westeros, the Lannisters eventually invited Andals into their realm and brought Andal youths to serve at Casterly Rock as wards and potential hostages. According to a lost scroll, Valyrian sorcerers believed their downfall would come from the Rock's gold.

Impressed by earlier visits to Casterly Rock and the Hightower, Roland I Arryn ordered the construction of the Eyrie as a replacement for the Gates of the Moon as the seat of House Arryn.

King Gerold Lannister raided the Iron Islands and held one hundred captives in the Rock. Gerold the Great then hanged a captive whenever the ironborn threatened his lands. Before becoming King of the Iron Islands, Harmund II Hoare spent his youth at Casterly Rock as a ward.

During Aegon's Conquest, King Loren I formed an alliance at Casterly Rock with Mern IX Gardener, King of the Reach, against Aegon the Conqueror. House Targaryen defeated the Lannisters and Gardeners at the Field of Fire, however. After the battle, Loren the Last surrendered his crown to Aegon and was confirmed as Lord of Casterly Rock and Warden of the West. Queen Visenya Targaryen is said to have been grateful that Loren rode to war instead of seeking refuge in his castle, as the Rock may have withstood even dragonflame.

### Iron Throne

Casterly Rock hosted King Aegon I Targaryen several times during his royal progresses.

After the ascension of King Maegor I Targaryen, Lyman Lannister hosted Prince Aegon and Princess Rhaena Targaryen at Casterly Rock, where the princess gave birth to Aerea and Rhaella at the Rock. The son of Jeyne Westerling was sent to Casterly Rock to be Lyman's ward.

After being expelled from Faircastle during the reign of King Jaehaerys I Targaryen, Rhaena flew from Fair Isle to the Rock on Dreamfyre. Lyman gave the Four-Headed Beast a suite within his castle, but Rhaena eventually left after becoming convinced that the Lord of Casterly Rock wanted her dragon eggs. Rhaena visited the Rock during her search throughout the Seven Kingdoms for the missing Aerea. Ser Alastor Reyne, master-at-arms of the Rock, participated in the tourney for the completion of the Dragonpit. Jaehaerys visited Casterly Rock during his progresses in 55 A.C. and 88 A.C.

### Dalton and the Dance

The young Princess Rhaenyra Targaryen was once courted during a feast at Casterly Rock by the twins Jason Lannister and Tyland Lannister.

House Lannister declared for the greens during the Dance of the Dragons. At the start of the civil war, Ser Tyland, Master of Coin to King Aegon II Targaryen, sent a quarter of the royal treasury from King's Landing to the Rock for safekeeping. The castle was left in disarray after the death of Jason in the Battle of the Red Fork and the Lannister defeat in the Battle by the Lakeshore, however. Prince Daemon Targaryen, husband to Aegon's rival Rhaenyra, suggested that Casterly Rock be stripped from the Lannisters and granted to Ser Hugh Hammer, but the queen declined.

The ironborn declared for Rhaenyra's blacks during the Dance. Although Dalton Greyjoy, Lord of the Iron Islands, was able to sack Lannisport, Casterly Rock was too strong for the ironborn once Jason's widow, Johanna Lannister, barred its gates. Johanna approved an expedition to recover Fair Isle from the ironborn, but the Red Kraken sent the heads of Ser Erwin Lannister and Lords Prester and Tarbeck to Johanna at the Rock after the plan was betrayed.

As the Dance wound down, Cregan Stark considered marching to subdue Oldtown and Casterly Rock. Johanna agreed to peace terms previously sent by Corlys Velaryon, however.

Dalton was slain at Faircastle in 133 A.C. When the fleet of Alyn Velaryon arrived in the Westerlands, Johanna presented him with a seahorse wrought in gold. Ser Leo Costayne invaded the Iron Islands, and the captured Rodrik Greyjoy was made into a fool at Casterly Rock.
