The Westeros seat of power just got even more menacing. At theGame of Thrones premiere event in San Francisico on Monday, HBO debuted a bigger version of its world-famous Iron Throne at its after-party at City Hall. Standing 11’ high and 8’ wide, it eclipses the original version (that’s 7’ high and 5’ wide). This is a bit more in line with George R.R. Martin’s original vision for the infamously uncomfortable Red Keep throne room’s chair forged from the countless swords of Aegon Targaryen’s conquered enemies. Here’s Dean-Charles Chapman (who plays King Tommen Baratheon) checking it out:

For an even better sense of scale, here’s another partygoer getting swallowed up by the seat:


By comparison, this is the original Iron Throne, as demonstrated by Sophie Turner (Sansa Stark):

But don’t expect to see this new version on the show (that would be weird if the Iron Throne just grew a few feet for no reason).
