Oldcastle
Castillo Viejo
Oldcastle is the seat of House Locke, standing in the North on the coast facing the Bite, south of White Harbor.
It served as a royal seat for the Locke kings during the Age of Heroes, and centuries later its name turns up tied to an urgent summons from the Wall.
Chapter 1
Seat of kings
Books only
Before the Lockes were just another northern lordly house, they ruled from here as kings in their own right, back in the days remembered as the Age of Heroes.
The castle was then more than a border stronghold: it was the capital of a kingdom that no longer exists, and that era is where its name comes from.
Chapter 2
A raven for Castle Black
Books only
When the wildling attack puts Castle Black in danger, Maester Aemon looks for help beyond the Wall, and one of the ravens he sends is bound for Oldcastle.
It is not the Night's Watch asking a casual favor: it is a call for help, sent to a northern seat that, centuries earlier, had been the capital of kings.
