Karlovac is a city located in central Croatia, situated at the confluence of four rivers – Kupa, Korana, Mrežnica, and Dobra. With a population of approximately 55,000 inhabitants, it is the administrative and cultural center of Karlovac County.


The city was founded in the 16th century as a military fortress by the Habsburg Monarchy, who wanted to protect their borders from Ottoman invasions. Its location at the confluence of four rivers made it strategically important, and the fortress served as a defensive line against the Ottomans. The fortress was designed in the shape of a six-pointed star, with a moat and ramparts surrounding it. The construction of the fortress was completed in 1579, and the city was named after the Austrian Archduke Charles II.

Throughout history, Karlovac was a center of military operations and played an important role in the Croatian War of Independence in the 1990s. The city was heavily damaged during the war, but it has since been rebuilt and restored.
