Ostrožac Castle, an national monument comprises a medieval fort, a fortress from the Ottoman period, a castle of Lothar von Berks and a collection of sculptures located in the natural surroundings of the castle.

Medievel Period


Dating back to 1286, Ostrožac was first documented as a property of Prince Babonjić from Blagaj. Witness the architectural marvels of this era with the construction of a defense tower on the northern side of the city, complemented by high walls, a drawbridge, armoury, bastions, and a casemate.

It’s believed that Ostrožac held significant importance, possibly serving as the residence for its rulers.

During the Ottoman invasion, General Ivan Lenković and 40 soldiers defended Ostrožac, making it a crucial part of the defense line against Ottoman attacks on Vojna Krajina. Despite their efforts, it wasn’t until November 13th, 1577, that Ferhad Pasha Sokolović successfully stormed and conquered the city after over a century-long struggle.

Ottoman period


Serving as the headquarters of the sanjak from 1578 until the Ottoman conquest of Bihać in 1592, Ostrožac emerged as a pivotal hub in the region. Following the relocation of the sanjak’s headquarters, Ostrožac became the center of one of the most strategically important captaincies within the Bosnian eyalet, encompassing Cazin, Stijena, Podzvizd, Peći, Kladuša, and Šturlić.

During the Ottoman era, Ostrožac thrived, boasting a formidable defense force of 4150 soldiers and 41 cannon, solidifying its status as the strongest town in the area. Governed by the esteemed Beširević family for nearly 300 years, Ostrožac witnessed remarkable construction endeavors, notably under the leadership of Osman agha Beširević. Osman agha fortified the city walls, constructing bastions equipped with basement rooms and erecting a building for the captain’s headquarters.

Austro-Hungarian Period


In 1896, Mehmed d Beširević, the final captain of Ostrožac, sold the fortress to Earl Lotar von Berks, then mayor of Bihać. Under his stewardship, Ostrožac underwent a remarkable transformation, marked by the restoration of the town and the construction of a magnificent castle in neo-Gothic style between 1900 and 1902.


The grand castle boasted an array of rooms, reception halls, and apartments, offering a glimpse into the opulence of the era. To enhance accessibility, Berks commissioned the construction of a serpentine road leading to the nearby River Una, where an ancient bridge already spanned its waters (built in 1872/1873), connecting to the old town.

The legacy of Berks endured beyond his lifetime, as his family continued to reside in the castle until 1932, utilizing it as a summer retreat even after relocating to Slavonia.

Ostrožac Sculpture Colony


The artistic legacy of Ostrožac through the renowned sculptor’s colony is established in 1967. Spearheaded by the Republican Fund for the Improvement of Cultural Activities and the Association of Artists of Bosnia and Herzegovina (ULUBiH), this initiative attracted artists and sculptors from around the globe to Bihać County, Cazin, and Ostrožac. Here, they meticulously crafted their works from bihacit, a stone renowned for its miraculous properties.
