Leaked pictures from the production set of “Game of Thrones” Season 6 show new structures being built for the show. New reports also suggest that the cast and crew may soon film scenes involving the Dothraki.

[Spoiler alert]

According to a report by LaVozdeAlmeria, filming for the popular TV series will begin at various locations in Spain in October. The producers have apparently hired about a hundred horses for filming a scene, suggesting that scenes of the Dothraki horsemen may be filmed soon.

The report suggests that one of the locations at Mesa Roldan may be used to film a scene showing the Tower of Joy from Westeros. According to the book series “A Song of Ice and Fire,” on which the TV series is based, the Tower of Joy is the location where Prince Rhaegar Targaryen kept Lyanna Stark during Robert Baratheon’s (Mark Addy) rebellion.

A flash back scene at this location may explain what really happened on the day Lyanna died. The scene is expected to confirm the fan theory that Jon Snow is really the son of Rhaegar and Lyanna.

More pictures from Almeria in Spain have been posted on DiariodeAlmeria. According to the report, filming for “Game of Thrones” Season 6 at this location will take place between Oct. 10 and Oct. 23.

Meanwhile, a new picture from the production set at Sallagh Brae has leaked online. The picture posted on LarneTimes shows a circular wooden structure being built, but the secrecy surrounding the popular TV series has kept details about what is being filmed here from leaking online.

According to the report, none of the cast members were seen at this location, which could have hinted at which part of Westeros was being depicted at this location. The report said that a scene involving 400 extras was previously filmed close to this location.

“Game of Thrones” Season 6 is expected to premiere sometime in April 2016.
