Game Of Thrones: 10 Leaked Season 6 Set Photos (And What They Mean)

A third castle the show will be filming at is the Castillo de Zafra, located in Guadalajara, Spain. When this was first revealed, there was a lot of speculation about what will be shot here, with the primary theory being a Tower of Joy flashback. Well, now Spanish language fan site Los Siete Reinos has confirmed that this is in fact what the castle will be used for.

It's not official from HBO, but if this report is correct, that is a huge deal. In the books, the Tower of Joy is the location where a fight went down at the end of Robert's Rebellion, and Lyanna Stark told Ned Stark some sort of secret and made him make a promise. The popular theory is that this has something to do with Jon Snow's parents, and that the series will be flashing back to the Tower of Joy to finally reveal that.  

If the show is filming a Tower of Joy sequence, that totally confirms that Jon Snow is coming back. After all, who cares about who Jon's parents are if he's just going to be burnt and never seen again? This is going to be one of those locations to scope out for the next few months, but just knowing that this will indeed be the Tower of Joy is the most glorious Season 6 spoiler yet.
