Shooting for the fifth series of the hit sex and swords fantasy drama will start in Belfast's Titanic Studios, which were recently visited by the Queen.
Cable giant HBO also revealed that some of season five will be shot in in Spain.
While the US television company did not reveal which part of Westeros the Province of Sevilla will represent, it is widely believed that it will be Dorne.
This is the home of Oberyn Martell, a fan favourite also known as the Red Viper and played by Pedro Pascal, who suffered a gruesome death in series four.
Primary shooting has been in Northern Ireland although Croatia and Iceland have also been used. Downhill Beach in Co Londonderry, the Dark Hedges in Ballymoney and Cushendall Caves in the Glens of Antrim have all been used as filming locations and the Paint Hall studios in the Titanic Quarter supports much of the CGI-driven scenes.
The show has already generated more than £87m for the economy and also created more than 900 full-time jobs and 5,700 part-time jobs.

Someone will break a promise to you, which is disappointing. Don't let this setback stop you from crossing the finish line. You may have to submit an entry late or attend the last few minutes of a meeting, but take heart. Rallying in the midst of difficult circumstances will count in your favour. Someone else may get a job or scholarship, but you'll be in the running for the next opportunity. In the meantime, have an alternative plan ready when relying on others for help.More
