The ruins of the fortress are located on Mount Hisarlaka in the Balkan Mountains - 3.4 km south in a straight line from the center of the village Kipilovo, in central Bulgaria.

The fortress was part of a system meant to defend Constantinople from the barbarian attacks from the north and it remained in use until the Second Bulgarian Empire.

The real tank from which the fortress was supplied with water is located in its south part.

Between the two reservoirs there is a foundation of a ruined building, with approximate dimensions of 9 by 6 m, oriented exactly east - west.

Outside the fortress there were not found any other buildings, except for a stone road, 4–5 m wide, which is partially preserved in its beginning.
