hbo 's hit series , game of thrones , is set to return with its much-anticipated fifth series , and that means the stunning settings where it was filmed are bracing for another influx of tourists .
while the programme has already filmed in some of the most picturesque places around the world - including croatia , iceland and the giant 's causeway in northern ireland - series five has opted for slightly warmer fare .
with much of the series set in a desert ruled by house martell , the cities of andalusia offer the perfect filming location for the ancient towns depicted in game of thrones .
