Ostrožac Castle is a castle located in Bosnia and Herzegovina in the Una-Sana Canton just outside the town of Cazin, in the village of Ostrožac. The castle dates back to the 13th century when Ostrožac was part of property of the noble house of Babonić family. In 1592 it was captured by the Ottoman Turks and established as an Ottoman province of Bosnia. The castle was built between 1900 and 1906 by Major of Bihać Lothar Von Berks as a birthday present for his wife, member of the Habsburg family.
Ownership of the castle is still disputed, but citizens of Cazin and Ostrožac are permitted to use the castle grounds for local concerts and entertainment. The castle is slowly being repaired.

The Hellenistic theater at Argos is cut into the hillside of the Larisa, with 90 steps up a steep incline, forming a narrow rectilinear cavea. Among the largest theaters in Greece, it held about 20,000 spectators and is divided by two landings into three horizontal sections. Staircases further divide the cavea into four cunei, corresponding to the tribes of Argos A high wall was erected to prevent unauthorized access into the theatron and may have helped the acoustics, but it is said the sound quality is still very good today.
Around 120 CE, both theaters were renovated in the Roman style.
