Gradačac Castle rises impressively from a hilltop in northeastern Bosnia, initiated in 1765 and completed during the 19th century by Husein Kapetan Gradaščević, known as the "Dragon of Bosnia." The fortress features 18-meter-high walls constructed between 1765 and 1821, and a 22-meter watchtower built in 1824 on Roman foundations. The castle's architecture reflects the layered influences of Ottoman and Austro-Hungarian periods, offering panoramic views of the surrounding valley and the charming town of Gradačac below. Designated a national monument, the castle stands as a symbol of Bosnian resistance against Ottoman rule and remains accessible via a short walk or taxi ride from the town center.
