Minecraft Game of Thrones project builds a blocky Westeros
The Eyrie is the home of the late John Ayrnn, whose death kicks off the plot. It's located high up in a gigantic mountain, and is thus nearly impossible to attack. TV veiwers may remember Tyrion being held here in series one, a problem that was eventually solved by Bron kicking a guy through a hole. Because Bron is awesome.
This build also has a time lapse video of its construction.
