[1] It is located close to the border with Croatia, lying on hillside terrain above the Korana river and its right tributary Mutnica.

The climate is medium continental, with cold winters and warm summers.

Throughout its history, Tržac appeared for the first time in the 11th century as a settlement in the central part of medieval Kingdom of Croatia.

The Ottoman Empire under Hasan Predojević conquered it by the end of the 16th century, pushing the Croatian defenders to the west, and converting the local population to Islam thus populating the area with Muslim inhabitants.
