The castle foundations date back to the 13th century, serving as the seat of the Blagajski dukes.
The Neo-Gothic palace section was commissioned by Count Lothar von Berks at the start of the 20th century.
The site contains a collection of modern stone sculptures from the 1960s and 1970s Yugoslavia, creating a striking contrast with the medieval walls.
The fortress was strategically located to oversee the Una River valley, a traditional border zone between different empires.
The castle has been designated as a national monument of Bosnia and Herzegovina to preserve its complex heritage.
Ostrožac Castle is a multi-layered historical site featuring an original medieval fortress, a 16th-century Ottoman fortification, and a Neo-Gothic residential palace built by the Lothringen family. It is situated on a rocky bluff overlooking the Una River in northwest Bosnia and Herzegovina. The site showcases a blend of architectural styles spanning from the 13th century to the early 20th century. During the Yugoslav era, the castle grounds hosted an international sculpture colony, resulting in a unique collection of permanent stone monuments scattered throughout the courtyard. The structures remain partially in a state of romantic decay, offering an unpolished, atmospheric exploration experience. The site serves as a museum and a venue for cultural events in the Bihać region.
