  ====The Eyrie====
  castle of Neuschwanstein, on which the Eyrie is based
  Based on the German castle of Neuschwanstein, the Eyrie is the seat of House Arryn. It is situated on the Giant's Lance and reachable only by a narrow mule trail, guarded by the Gates of the Moon and three small castles, titled Stone, Snow, and Sky. Travelers must enter the Gates of the Moon and its upper bailey before reaching the narrow path up the mountain. The steps up the Giant's Lance starts directly behind the Gates of the Moon. The Eyrie clings to the mountain and is six hundred feet above Sky. The last part of the climb to the Eyrie is something of a cross between a chimney and a stone ladder, which leads to the Eyrie's cellar entrance. Due to the Mountains of the Moon's harsh winters, travel to and from the Eyrie is possible through the mountains only in summer.
  The Eyrie is the smallest of the great castles in the story, consisting of seven slim towers bunched tightly together. It has no stables, kennels, or smithies, but the towers can house 500 men, and the granary can sustain a small household for a year or more. The Eyrie does not keep livestock on hand; all dairy produce, meats, fruits, vegetables, etc., must be brought from the Vale below. Its cellars hold six great winches with long iron chains to draw supplies and occasionally guests from below, with oxen are used to raise and lower them. Winter snows can make supplying the fortress impossible. The Eyrie's dungeons, known as "sky cells", are left open to the sky on one side and have sloping floors that put prisoners in danger of slipping or rolling off the edge. Executions in the Eyrie are carried out via the Moon Door, which opens from the high hall onto a 600-foot drop.
  The Eyrie is made of pale stone and primarily decorated with the blue and white colors of House Arryn. Elegant details provide warmth and comfort through plentiful fireplaces, carpets, and luxurious fabrics. Many of the chambers have been described to be warm and comfortable, with magnificent views of the Vale, the Mountains of the Moon, or the waterfall. The Maiden's Tower is the easternmost of the seven slender towers, so all the Vale can be seen from its windows and balconies. The apartments of the Lady of the Eyrie open over a small garden planted with blue flowers and ringed by white towers, containing grass and scattered statuary, with the central statue of a weeping woman believed to be Alyssa Arryn, around low, flowering shrubs. The lord's chambers have doors of solid oak, and plush velvet curtains covering windows of small rhomboid panes of glass. The High Hall has a blue silk carpet leading to the carved weirwood thrones of the Lord and Lady Arryn. The floors and walls are of milk-white marble veined with blue. Daylight enters down through high narrow arched windows along the eastern wall, and there are some fifty high iron sconces where torches may be lit.
  The Eyrie was held by Lord Jon Arryn, who fostered Ned Stark and Robert Baratheon prior to Robert's Rebellion. After the war, Lord Arryn served as King Robert I Baratheon's Hand of the King (prime minister). After Lord Arryn was assassinated, his wife, Lady Lysa Arryn, took her sickly child, Robin, and fled to the Eyrie. Lysa refused to align herself with any of the claimants during the War of the Five Kings, but eventually pretends to a possible alliance with House Lannister after Lord Petyr Baelish agrees to marry her. Later Baelish kills Lysa after she attempts to murder her niece, Sansa Stark. As of ''Feast for Crows'', Baelish rules in the Eyrie as the Lord Protector and Regent for the sickly, epileptic Lord Robert "Robin" Arryn, and plans for Sansa to marry Harold Harding, who will become heir to the Eyrie and the Vale in the event of young Robin Arryn's death.
  For the CGI compositions of the Vale of Arryn in the TV series, as seen in the establishing shot of the Eyrie and from the sky cells, the visual effects team used images and textures from the Greek rock formations of Meteora. Initially they had been considering the Zhangjiajie Mountains in China, but because the landscape base plates were shot in Northern Ireland, using Meteora resulted a better option. Set designer Gemma Jackson said, "A lot of the mosaics in the Eyrie were based on a beautiful chapel I visited in Rome." The interior of the High Hall of the Arryns was filmed at The Paint Hall, occupying one of the four soundstages there. Martin acknowledged that the set differed significantly from its presentation in the books: "In the books, the room is long and rectangular. But The Paint Hall soundstage had essentially a square space, which they chose to put a round hall in, with a staircase curving up to a throne that was high above."
