I think Dubrovnik is the most famous city in Croatia. In 1979, the city of Dubrovnik was added to the UNESCO list of World Heritage Sites in recognition of its outstanding medieval architecture and fortified old town. Probably is the most expensive city in Croatia. 10eu/hour parking, just saying.. Dubrovnik was the main filming location in Croatia for King's Landing, a fictional city in Game of Thrones. Probably every fan of Game of Thrones will like to visit this city. Every fame brings its negatives, too much people and crowd. Probably this is a city for short stays, for me.
