MADRID – A portion of “Game of Thrones’” fifth season will shoot in several natural locations in the province of Seville, Andalusia, HBO announced Wednesday.

Peter Welter Soler’s Fresco Film Services will provide production services in Spain. The Andalusia Film Commission, Seville Film Office and Osuna Film Office will support the filming, which will take place later in 2014.

The announcement confirms an observation made in late May by James Costas, the U.S. Ambassador to Spain and a former HBO VP of global licensing and retail, that the U.S. pay TV giant was in “firm negotiations” with the Andalusia Film Commission to find locations in Spain.

Exact locations will be confirmed closer to the time of production, HBO said Wednesday. That will do nothing to stem speculation about which locations will be used for what setting of “Game of Thrones,” which will visit Oberyn Martell’s native Dorne in season 5.

Inclusion of the Osuna Film Office suggests HBO may feature its most celebrated landmark, the Osuna University, a singular rectangular mole built in the Italian Renaissance style and topped by four cylindrical spires with blue-glazed ceramic coating.

According to Spain’s radio station Cadena Ser, Seville’s spectacular Alcazar — a former fort and now still-used royal palace, with a Moorish courtyard, reflecting pool and sunken gardens — will be transformed into the Water Gardens of Dorne, the private residence of the House of Martell, and a favorite place of Prince Doran Martell.

Spain hence joins Iceland, Croatia and Northern Ireland as a location for “Game of Thrones,” whose fifth season will begin filming in Belfast later this month.
