Casterly Rock

 

Casterly Rock is the ancestral stronghold of House Lannister. It is located on the Western coast of Westeros on a rocky promontory overlooking theSunset Sea. It overlooks the major city of Lannisport. A major goldmine is located under Casterly Rock. It is one of the most productive in the realm and provides House Lannister with their wealth.

Lann the Clever swindled Casterly Rock from House Casterly.

According to tradition, the castle was originally held by the House Casterly, the old Kings of the Rock. They were hoodwinked into giving the Rock toLann the Clever, a legendary trickster and ancestor of House Lannister, thousands of years ago, during the Age of Heroes.
