For landmark approval - Old City of Dubrovnik: in the book author mentions Dubrovnik several times, because of the siege that was focused on the old part of the city. https://en.m.wikipedia.org/wiki/Siege_of_Dubrovnik
(my translation: If there are churches (Cathedral in Šibenik), old cities (Dubrovnik, Zadar, Šibenik) ...)
