Being of Croatian descent myself it's cool to read that the Qarth scenes from Game of Thrones are filmed in Dubrovnik! I'd love to visit Croatia sometime.
If you've watched the show and wondered where all the exotic, arid, desert footage was shot for the 'Qarth' kingdom scenes, HBO said they are mostly filmed in Croatia.
The premium cable channel works with a production company called Embassy Films, based in Croatia, for the scenes shot there. About 170 local crew were employed for shooting in Dubrovnik, according to the production company.
"This was very good for Croatian, Dubrovnik economy, starting from crew and people directly involved, to hotels, transportation, etc.," said Erika Milutin, executive producer working on the show with Embassy Films.
