Shepherding tourists through the arches and towers of Croatia’s medieval walled city of Dubrovnik, Ivan Vukovic spends half his time leading tours of a capital that doesn’t exist: the fictional King’s Landing from Game Of Thrones (GoT).

The two cities now rival each other for fame after Dubrovnik – already a tourist and cruise ship magnet – became a set in 2011 for the cult HBO series, whose final episode will broadcast on the morning of May 20 (in Malaysia).
