  ===Filming locations===
  The episode used locations in four different countries: The Paint Hall in Belfast, the City Walls of Dubrovnik, Mývatn and Vinderbelgjarfjall, and the Old Fort at Essaouira.
  The production continued to use the Paint Hall studios in Belfast for most interior shoots. The scene of Daenerys at sea was filmed at the Linen Mill Film & Television Studios at Banbridge, using the same ship built for Theon's arrival in Pyke and used as Stannis' flagship in season 2. The beach of Downhill Strand returned as the island of Dragonstone.
  The old city of Dubrovnik was again used for the exterior shots of the capital, King's Landing. Tyrion and Bronn are seen walking on the famed city walls, and the scene where Lord Baelish visits Sansa at the docks was filmed in the old port between Fort Lovrijenac and the Pila Gates.
  Also repeating from last season, the scenes beyond the Wall were filmed in Iceland. The Wildling's camp was built in a new location, on a lava field in the Mývatn Lake region in the North, a few hours from the town of Akureyri. Building the camp took months of work from the art department and weeks of construction by the local crew. Although the scenes at the Icelandic exteriors were filmed at minus 11 degrees Celsius, the interior of Mance's tent was filmed on one of the soundstages at the Paint Hall. The fires burning inside the tent made the set very hot, and the actors suffered the heat wearing heavy furs designed for Arctic climates.
  To depict the slaver city of Astapor, the production used the Moroccan city of Essaouira. The Unsullied are introduced in the city ramparts of ''Skala de la Ville'', the 18th-century sea bastion that runs along the northern cliffs, and during the closing scene when Barristan reveals himself, the Genoese-built citadel by the harbour can be clearly seen.
