Soko Grad (Соко Град), also known as Sokolac, was a medieval city and fortress 2 km east of Sokobanja. The fortress was declared a Monument of Culture of Great Importance in 1982, and it is protected by Republic of Serbia. The fortress was founded in the 6th century during the reign of Emperor Justinian I, to prevent incursions of Pannonian Avars and Slavs into the Balkan peninsula. In 1172, it was occupied by Stefan Nemanja and became part of the medieval Serbian state. The Ottoman Empire occupied it in 1398. The town was destroyed by the Ottomans during a conflict, and today the only visible remains of the upper town are the gate, walls, and three towers.
