I’m a big fan of transport maps, I’m a big fan of maps of fictional places and, of course, I’m a big fan of Game of Thrones. So this map of Westeros based on US Subway systems (would have been nice if it was the London Underground instead, but oh well) is incredible. The level of detail and accuracy that its creator, Michael Tyznik, has put into it is crazy.
The map, and an extended map of all known lands in the books, are available to buy as prints. I need one for my flat.
