ARMAGH, Northern Ireland (Circa) - The cost of living in Westeros? About $656,000.
That's how much it will cost to purchase the Gosford Castle, better known to fans of the uber-popular HBO show "Game of Thrones" as Riverrun. The structure, located in Northern Ireland, is 200 years old and is on sale.
In GOT, the castle is the childhood home of Lady Catelyn Stark and the ancestral home of her family, House Tully.
If you're looking for more bang for your buck, Airbnb has offered to give a room in the castle a "Game of Thrones"-style makeover should the new owner be cool with listing it on the popular home-sharing website, according to CNN.
