context_page_description: The Ostrovica Castle is a large medieval structure situated above the small village of Ostrovica near Kulen Vakuf, Bihać municipality, Bosnia and Herzegovina. Having been built on a woody ridge of a steep hill overlooking left bank of the shallow Una river, the castle was located on a strategic site connecting the northern and southern parts of the long Una valley.
  The modern-day castle was most probably built during the 15th century on the foundations of ancient fortification which dates back to ancient Roman times or even earlier.
