We have finally seen Valyria in season 5. Can anyone tell me where the Valyria scene was filmed?
Valyria scene was filmed at Toome, County Antrim, Northern Ireland. Seams though the place went under drastic changes during post production. Only the bridge where Tyrion and Jorah were attacked is a real place, rest of ruins just CGI.
To back this up here are sources:
Game of Thrones Season 5: Episode #5 - The Stone Men of Valyria (HBO) video from GameofThrones channel shows the place where filming took part. Though the real place is not revealed in this video, river and a ruined bridge gave something to start search with...
So some googling brought me to this watchersonthewall.
Now, here's image from watchersonthewall site. Tweet states that this bridge is in Toome.
and this is captured from the youtube video
though the angle is different resemblance is hard to not notice.
