Soko Grad, also known as Sokolac, is a medieval city and fortress located 2 km east of the spa town of Sokobanja, Serbia.
The fortress was founded in the 6th century during the reign of Eastern Roman Emperor Justinian I, to prevent incursions of Eurasian Avars and Slavs into Balkan peninsula.
In 1172, it was occupied byStefan Nemanja and became part of the medieval Serbian state.
Turks from the Ottoman Empire occupied it at the end of the 14th century, in the year 1398. The town was destroyed in a violent Turk attack, and today, the only thing visible is the remains of the upper town with a gate, walls, and three towers.
