In season 7 of ‘Game of Thrones’, the old shipyards were disguised as the catacombs of the Red Fortress, in King’s Landing, where some dragon skeletons still remain. In there, in season 2, maester Qyburn shows Cersei the Scorpion, a huge crossbow which she could use to kill Danaery’s dragons. In season 6, Tyrion meets Jaime there, through Bronn of the Blackwater, to ask him to convince Cersei of the advisability of a meeting to discuss the imminent attack of the White Walkers.
In ‘La Peste‘, the Reales Atarazanas represents the Royal Prison, where the main character, Mateo Nuñez (Pablo Molinero), walk among numerous prisoners seeking Valerio, and where they play cards and celebrate parties with wine and prostitutes. Some scenes set in the cloth factory where the prostitutes are in the upper side of the old shipyards were also shot here.
