Ostrožac Castle stands on a hill above the Una river near Cazin, in the far northwest of Bosnia. It started as a medieval fortress, became an Ottoman stronghold in 1592, and was rebuilt in the early 1900s as a romantic castle by Lothar von Berks, the mayor of Bihać. The three periods are still visible in its towers and walls. Its courtyard holds an open-air sculpture park of more than 150 large stone works made by artists at the sculptors' colony held here for over 50 years. It is a protected National Monument.
