Winterfell

Background
According to legend, House Stark has held a castle at Winterfell for 8,000 years, though it has been considerably expanded over the centuries.[7]

Eddard Stark rode south to fight in Robert's Rebellion after his father and older brother were killed by the Mad King. At the end of the war, he returned to Winterfell with his new wife Catelyn Tully, their infant son Robb Stark, and also Eddard's nephew Jon Snow, who he raised as a son at the behest of Jon's mother, Lyanna Stark. After the Greyjoy Rebellion eight years later, Eddard tookTheon Greyjoy back to Winterfell as his ward - partly as a political hostage, but perhaps partially to raise him to be an honorable man.[8
