Minecraft Game of Thrones project builds a blocky Westeros
While Lannisport may be the home of the Lannisters, Casterly Rock is their stronghold. You know, for the longest time while watching the show I thought this was called 'Castley Rock' as in 'a rock that's a bit like a castle.' I was disappointed to find out that it was just me hearing it wrong, not that the Lannisters were secretly crap at naming things.
This build also has a time lapse video.
