Dubovac Old Town is one of Croatia’s most beautiful and best-preserved monuments of feudal architecture. Situated atop a prehistoric mound overlooking the Kupa River, it owes its name to the dense oak forests that once surrounded it. Throughout history, it has changed hands among various noble families and undergone structural transformations; its current appearance is the result of a thorough 20th-century restoration. Here, visitors can enjoy a fairytale-like medieval courtyard, visit the museum inside the *Branič-kula* (Defense Tower), and take in the most stunning view of Karlovac at dusk.
Zvijezda is the historic core and oldest part of Karlovac, established on July 13, 1579, in the shape of a perfect six-pointed star. Today, this unique defensive fortress is filled with a network of charming streets, Baroque palaces, museums, and Croatia’s oldest music school. The former defensive moats have been transformed into green parks; a walk beneath the chestnut and linden trees alongside the remains of stone ramparts offers visitors a magical journey into the past and an unmissable tourist experience.
Aquatika is a unique freshwater aquarium showcasing the rich aquatic life of Croatia’s rivers and lakes. The exhibition follows the course of a typical karst river from source to mouth, providing an educational and exciting insight into river flora and fauna. The main attractions include giant specimens of ancient sturgeon, as well as fascinating facts about fish behavior and life cycles. Aquatika brings together the natural heritage, history, and traditions of the four rivers of Karlovac—the Korana, Kupa, Mrežnica, and Dobra—making it a perfect destination for all ages.
Situated at a historically significant defensive point of the city, the Homeland War Museum in Turanj stands as a testament to the struggle for freedom and an independent Croatia. A modern, interactive museum space has been created within the renovated building, which defenders nicknamed “Hotel California.” The permanent exhibition features around 350 original artifacts alongside hours of multimedia content, films, and animations. With an outdoor exhibition area showcasing military hardware and an educational corner for the youngest visitors, the museum offers a moving and educational account of the nation’s history.
Perched on a steep cliff above the sparkling Kupa River, Ozalj Old Town is one of the most beautiful castles in northwestern Croatia. This historic symbol of the city of the Zrinski and Frankopan noble families lies just 20 kilometers from Karlovac and 60 kilometers from Zagreb, making it an ideal destination for a day trip. The fortress’s current Baroque appearance conceals a rich architectural past, while its interior houses the Local History Museum. Through an exhibition spanning 6,000 years of history, the museum also pays special tribute to the work of the renowned painter Slava Raškaj.
The Nikola Tesla Experience Center in Karlovac is an interactive space dedicated to the famous inventor who attended school in this city. This is not a traditional museum, but a dynamic venue where visitors become active participants through experiments, technology, tablets, animations, and mind games. Here, you can discover tamed lightning and levitating tablets, and learn how Tesla foresaw the mobile phones we use today. The Center offers a fun, educational, and inspiring experience for children, families, and all enthusiasts of science and innovation.
Situated at the foot of the Dubovac Old Town, bordering a centuries-old forest, the National Shrine of St. Joseph was the first church built in Karlovac after World War II. Featuring modern architecture, the church harmoniously blends natural tranquility with sacred heritage. St. Joseph is the patron saint of Karlovac, and his feast day is celebrated on March 19th. Due to its exceptional spiritual and historical significance, the shrine was designated a Papal Minor Basilica in 2026, making it a unique place of peace and prayer.
Bosiljevo Castle is a fairytale-like, mysterious fortress situated on a steep cliff above a small spring and a former lake. Surrounded by a well-preserved park—itself a protected monument of landscape architecture—the castle seems to have sprung up right on the boundary between reality and the wondrous. Built amidst the profound tranquility of a dense forest, Bosiljevo has changed its appearance over the centuries; yet, its oldest section, perched on the rocky crag, continues to captivate visitors with its mystical beauty and rich noble heritage.
Nestled in a picturesque landscape of wooded hills above the Dobra River, the ruins of the old town of Novigrad bear witness to the region’s former administrative and military importance. The historic Carolina Road runs past the fortress, spanning the river with a beautiful stone bridge dating back to the early 18th century. On the opposite bank lies the old village of Crkveno Selo, home to the Parish Church of the Assumption of Mary, creating an idyllic blend of natural beauty, architectural heritage, and historic routes.
