The Magheramorne Quarry in Northern Ireland has served as the backdrop and set for both Hardhome, the scene of the epic white walker attack on the Free Folk in season 5 (though it’s not a battle that takes place in the books). Side note: The Iron Islands, where Theon Greyjoy/Reek comes from, is set in Ballintoy Harbour and Murlough Bay in Northern Ireland.
