Every Game of Thrones Spoiler We Know for Season 7

We will see Casterly Rock

The Lannisters have talked often enough about Casterly Rock, the Lannister family base of operations. But while we’ve seen the homes of some of the other great Westerosi families — Winterfell for the Starks, the Eyrie for the Arryns, etc. — we have yet to lay eyes on it. According to Watchers on the Wall, that will change in season 7.

Why will the show visit Casterly Rock? That’s harder to say, although with Daenerys intent on conquering the Seven Kingdoms, it would make sense for her or her soldiers to pay it a visit. Tyrion, who grew up there and knows its defenses, could be a big help if Daenerys wants to conquer it, and remember that Daario suggested attacking Casterly Rock from the west in the season 6 finale. Our best guess — and it is a guess — is that Daenerys sends Grey Worm and some of the Unsullied to take it. We say this because actor Jacob Anderson was spotted on set at the Castillo de Almodóvar del Río in Spain…

…around the time it had a Lannister flag flying from it.

Looks like it could have stood in for Casterly Rock to us.

But some of this is speculative. We have more specifics on a different famous castle, another one we’ve heard a lot about but have yet to see. Read on.
