Looking at the picture above it's tough to believe that it's on this planet, let alone sitting on the coast of Northern Ireland. The Giant's Causeway is just one of the nation's jaw-dropping beauty spots, and while it hasn't featured in Thrones, plenty of Northern Ireland has. Filming has taken place in castles and stunning natural surroundings across the whole region, and it's thought that Thrones' presence has injected $100 million into the Northern Irish economy, with tourists travelling in from far and wide to get a glimpse of their favourite locations.
