It is located in Pirot, built in the 14th century. It was in the middle of Serbian -Turkish conflict. Fort was in military use until the first half of the twentieth century. Today, it is largely preserved, and archaeological research is carried out, followed by work on restoration and conservation. Serbian medieval fortress is relatively small, and consisted of a citadel defended by the tower. Later in the eighteenth century, another building was raised, with weaker wall with crenelles, facing the river Bistrica.
