First, Croatia is the homeland of the necktie; the modern cravat originated from 17th-century Croatian mercenaries who wore distinct scarves that caught the eye of King Louis XIV in France. Second, the city of Zadar features the world's only Sea Organ, an architectural masterpiece that uses the movement of the Adriatic waves through 35 underwater pipes to create a hauntingly beautiful, ever-changing musical symphony. Third, Croatia is home to the world's smallest town, Hum, located on the Istrian Peninsula; despite its tiny population of approximately 50 residents, it maintains its medieval status and holds a Guinness World Record. Additionally, fans of pop culture often visit Croatia because it served as the primary filming location for King's Landing in Game of Thrones, specifically the historic stone walls and orange-roofed buildings of Dubrovnik.
