A picture of the Game of Thrones film crew setting up around Gosford Castle has recently been tweeted by @digitalroy. Last year Gosford Castle was used as the set for scenes in Riverrun. We have no confirmation of what Gosford Castle will be used for in Season 4 as of yet.
Cat Taylor, the writer of the Behind-the-Scenes segments on Game of Thrones, was asked if they were shooting Riverrun scenes at Gosford again, this is what she had to say about that.
@ash_eng @westendted Riverrun? No, no. :P

So if Gosford Castle isn't going to be used as Riverrun what other Westerosi location may Gosford Castle be used for? As always, Please let me know your thoughts in the comments.
