Sokolac Fortress is a medieval stronghold near Bihać that dates back to documented records from 1395, though its exact origins lie earlier in the region's history. Located strategically to control territorial boundaries during the Kingdom of Hungary period, it endured numerous medieval conflicts before falling under Ottoman rule in 1592 following the capture of Bihać. By the 19th century, the fortress served as a minor garrison with reduced fortifications. Declared a national monument in 2008, the site represents an important layer of Bosnia's medieval and Ottoman heritage, though assessments indicate the structure requires significant restoration efforts.
