A little bit of history
The City of Karlovac started life as a fortified military outpost whose purpose was to strengthen the southern borders of the Austro-Hungarian Empire against Ottoman invasions. Construction of Karlstadt (as it was called then) began on 13th July 1579 under the instruction of Archduke Charles II of Austria (“Karl” in German. So, Karl-stadt, or Charles’ Town in English… get it?!). Karlovac’ birthday is still celebrated with a big party every year on this day!
The fortifications were designed to be in the unique shape of a six-pointed star, while the geometric grid inner core of houses, palaces, squares, and military buildings was typical of ideal renaissance urban planning. Unique also was its chosen location: on the crossroads of paths from the Pannonian plains to the Adriatic coast and the confluence of four rivers - Mrežnica, Korana, Kupa and Dobra.
