Karlovac is a city in central Croatia, 56 km southwest of Zagreb and 130 km north-east of the Rijeka. Located on the edge of the Pannonian Plain. It was founded as a fortress for the protection of the Turkish conquest, in the plain at the confluence of the Korana River, at the foot of the ancient ruins of Dubovac. It’s named after its founder, the Austrian archduke Carl. It is built on the idea of an ideal Renaissance city in the form of a six-pointed star with a central square and streets intersecting at right angles. During the 18th and 19th centuries, largely thanks to a booming trade and shipping at river Kupa, Karlovac is reputed for one of the richest Croatian cities. It’s a city on four rivers: Kupa, Korana, Mreznica and Dobra. It has Croatian version of Oktoberfest.
