The Game of Thrones prequel series reportedly shut down filming at a key international location after extreme weather conditions left parts of the set unusable. Storm Therese reportedly cancels A Knight of the Seven Kingdoms Season 2 filming Storm Therese has forced HBO to halt A Knight of the Seven Kingdoms Season 2 filming at Gran Canaria’s Las Niñas Dam.

Atlantico Hoy reports that severe flooding submerged portions of the production set built near the reservoir. The crew has since relocated operations to mainland Spain to resume shooting. The storm brought the heaviest rainfall the region had experienced in 15 years, dramatically raising water levels at the dam.

Gran Canaria’s Environment Minister Raul Garcia Brink confirmed the production company abandoned the island location. The site had been contractually reserved for filming from February 23 through May 15. HBO selected the Canary Islands to film barren landscapes depicting a drought storyline from George R.R.

Martin’s source material. Production originally launched in Belfast, Ireland, before shifting to Gran Canaria for its rugged terrain. Spain has served as a key filming location for the Game of Thrones franchise since its fifth season.

The crew now faces the task of submitting a formal action plan for removing the submerged set. Work will begin once water levels recede enough to allow safe access to the site. Environmental compensation efforts have already included planting 50 Canary Island pines and additional forestry improvements.

Reports suggest the production already completed most of its scheduled filming before the storm struck. The shoot was originally set to wrap by June 2026, with HBO targeting a 2027 release window. The nearby campsite reopened on April 11, marking the first public sign that filming had stopped.

HBO has not commented on the disruption or any potential schedule changes. Showrunner Ira Parker previously outlined ambitions for a 12 to 15 season run drawing from Martin’s Hedge Knight series. The first season drew over 24 million viewers per episode for HBO and earned a 94% rating on Rotten Tomatoes. A Knight of the Seven Kingdoms Season 1 currently streams on Max.
