Winterfell

Winterfell is the ancestral castle and seat of power of House Stark and is considered to be the capital of the North. It is located in the center of the northern province of the Seven Kingdoms. It was supposedly built by Brandon the Builder over eight thousand years ago, with the help of giants. For most of recorded history Winterfell was the seat of House Stark, the Kings in the North and later as Wardens of The North, after King Torrhen Stark bent the knee to Aegon the Conqueror and his dragons. As the regional capital of the North, harvest festivities have been hosted in Winterfell for centuries. Wiki - Game of thrones.
