Karlovac is the city where the most important railway and road routes connect the capital Zagreb with Rijeka, Split and other parts of Croatia. In fact, Karlovac has always been a city center that connects Europe with the Adriatic ports, as evidenced by the old historic roads of Karolina, Jozefina, and Lujzijana, thanks to which Karlovac has developed into an important commercial and transport center.
The excellent geo-traffic position is also evidenced by the distance of Karlovac from some of the major European cities. The distance from Karlovac to Ljubljana is 104 km air distance, from Karlovac to Sarajevo 386 km, to Budapest 400 km and to the Austrian capital, Vienna – 410 km. The city of Karlovac is the administrative, political, cultural and sports center of Karlovac County which is divided into 5 major cities (Karlovac, Duga Resa, Ogulin, Slunj, and Ozalj), and a total of 17 municipalities. The city of Karlovac itself consists of 18 neighborhoods, the most prominent of which are: Stari Centar – which is the oldest gentlemanly city district and the seat of the leaders who built the town of Karlovac. Borlin is the district where Karlovac brewery is located and which is one of the most beautiful districts in Karlovac. In addition to being the most beautiful, it is known as the district with the cleanest water which the brewery uses to make beer.

Natural sights in Karlovac

The most prominent natural sights in Karlovac are its four rivers Kupa, Mrežnica, Dobra, and Korana.

The Kupa river that springs into the Risnjak National Park is the longest of the four rivers that flow through Karlovac. What makes the Kupa stand out is the fact that, although it springs only 30 km from the Adriatic Sea, its course goes inland, which is not characteristic of any other river in the world. In 1908. the Ozalj-Munjara hydroelectric power station was built on the Kupa River in Ozalj, which contributed to the development of the Karlovac economy.
Mrežnica river is a beautiful river, rich in waterfalls and cascades. With its cleanliness and temperature suitable for swimming, it is a favorite holiday spot for many visitors from Zagreb and the Karlovac area.
The Dobra River has two sources and is characterized by underground and above-ground flows. It is 107 km long. Dobra disappears underground in Ogulin, in the Djulin abyss and resumes its above-ground flow at the village of Gojak, where the Gojak hydroelectric power plant is.
Throughout history, the first parks, baths, and hotels were created along the Korana, and today the Korana is a place where Karlovac citizens gather for swimming, sports, and entertainment.
The historian Radovinovic described his experience of Karlovac as “a city in a park”, and Karlovac is indeed a city rich in parks, promenades and generally greenery. The construction of parks began at the time of the construction of the city fortress, and to this day the Karlovac people pay great attention to environmental care.
Karlovac ranks first in Croatia by the number of parks, relative to its urban area. The natural beauty and environment of Karlovac were also recognized by the Croatian National Tourist Board, which in 2010. presented the “Green Flower Award” to Karlovac for the most decorated city of continental Croatia. If you want to spend the day outdoors and enjoy a walk in some of the most beautiful parks and promenades in Karlovac, you definitely have to visit the Marmont Plane Alley located in Dubovac, which is characterized by the 200-year-old plane tree avenue planted in 1809. – by the order of August Marmont, Napoleon’s marshal.
The alley is 850 m long and there was originally planted 112 maple leaf trees. In 1968. the plane tree alley was entered in the register of specially protected natural objects. Another unforgettable and beautiful promenade is the Grand promenade (today the promenade of Dr. Franjo Tudjman), which is located around the Star of Karlovac and is one of the most important centers of social life in Karlovac today.
During the rebuilding from 1886. to 1888. trees were planted on the promenade in five rows, the scene which still stands out today. The large promenade extends along with the 11 most famous civic houses and villas from the second half of the 19th century – from “Kavana” to “Zorin dom”. Other green areas ideal for walking include: Renaissance park along the University of Karlovac, the avenue of linden trees at the remains of the fortification ramparts, the Black Promenade between the street of Draskovic and the road of D. Trstenjaka, the Arboretum at the Forestry School, Modrusanov Park and the unique Vrbanic park, which was opened to the public in 1896. The idea for the park was accepted by the then-mayor and pharmacist Josip Vrbanic, at the initiative of the Society for the Beautification of the City, and it was conceived as a small botanical garden in the open. The Vrbanic park is located in the south-east part of the town, between the river Korana and the famous Karlovac “Star”, and it consists of three parts: the English part of the park, the French part and the third part where coniferous spruce and fir trees predominate. Korzo, or in Italian, “Corso” represents the main city street or promenade. The Karlovac korzo is considered to be Petar Zrinski Street, which extends from the river Kupa to the green promenade near the Star of Karlovac.

History of Karlovac

The town of Karlovac was built in the 16th century in the area where four rivers flow, at the foot of the old town of Dubovac. It was founded as a fortress in the shape of a six-pointed star and its main task was the defense against the Turkish invaders. The exact date of the construction of Karlovac was the 13th of July in 1579. and the name Karlovac was given in honor of its founder – the Austrian archduke Karl Habsburg.

The last Turkish siege of Karlovac was in 1672. Throughout history, the city has experienced many disasters, from floods and fires to plague. The largest fire occurred in 1594. when the entire city was burned. The plague epidemic in 1773. was extremely severe and almost half of the population died as a result.

At the time, during the 16th and 17th centuries, Karlovac was under military rule. The citizens of Karlovac believed that the military administration was hampering the development of Karlovac’s economy and trade, and they fought to declare Karlovac a “Free Royal City”.

At its session of the 25th of February in 1770. the Croatian parliament demanded that the Croatian coast must be returned to Croatia and that the city of Karlovac is declared a “Free Royal City” and annexed to Civil Croatia. After seven years, Queen Mary Theresa, by her writing on August 9th, 1776. determined that the city of Karlovac should be given the position of a free city.

In the 18th and 19th century Karlovac experienced its first “Golden age” and became the main trading center between the Adriatic Sea and the Podunavlje region. At that time, the most famous roads were Karolina (connecting Karlovac and Rijeka), Jozefina (connecting Karlovac and Senj) and Lujzijana (Karlovac-Rijeka). The Lujzijana road was the shortest link between Karlovac and the city of Rijeka, and one of the most modern roads in the entire monarchy. With the development of shipbuilding on the river Kupa during the 19th century, Karlovac experienced its second “Golden age”.

Karlovac slowly grew and grew, so that in the early 20th century it was the third city in Croatia in terms of population and economy. During World War 2, from 1941. to 1945. the city experienced one of the most difficult periods of its history. During the 20th century, Karlovac changed a lot, so that it grew from a former industrial city into a true political, cultural and social center. More recently, during the Homeland War, Karlovac was a key point in Croatia’s defense. There were many casualties in the attacks on the city and the city itself suffered tremendous economic damage.

Dubovac is an old town for whom it is not known when exactly it was created. It is believed to date from the 13th century and long before Karlovac is mentioned in books. It is located above Karlovac, on the hill above the river Kupa and represents the oldest Karlovac monument.
Dubovac was named after the dub (oak) and the oak forest that surrounded it. From the Dubovac viewpoint, there is a beautiful view of the whole Karlovac.
The historical and cultural core of the Old Town of Karlovac was built in the form of a six-pointed star, which is why it was named the Karlovac Star. The Star consists of a central square and streets intersecting at right angles. As Karlovac was built as a fortress, the star shape was perfect for defending against enemies.
For lovers of culture and theater, it will be interesting to visit the Zorin dom City Theater or one of the city’s galleries. The Zorin dom Theater was opened in 1892. after which Karlovac slowly became one of the strongest centers of the art and theater scene. Until the opening of the hall, improvisations and performances were held throughout the inns, cafes and home stages.
The Karlovac Theater or the National City Theater Karlovac has been operating professionally since 1948. The Ivan Goran Kovačić City Library is the oldest and largest cultural institution in Karlovac, and the entire Karlovac County and is also one of the five largest public libraries in Croatia. The city library was created during the Illyrian movement following the decision of the then prominent and powerful men of the city. Her first name was “Illyrian Reading Society”. From that time until today it has remained as a center of culture, history, and literacy in the town of Karlovac.
