It remains one of the biggest historical defensive fortifications in the country with an area of 6,296 square metres (67,770 sq ft).

The fortress is located on a steep cliff around which Tešanj city centre eventually was formed.

It is accessible only from one side which had provided it with a good defensive advantage against any incoming forces.

[3] No current historical sources identify the exact year of its construction or who its constructor was.

The early foundation of this fortification had started some time during the Bronze Age[3] and it was later gradually expanded by the Romans, Slavs and Ottomans.
