The layout of Upper Town is based on irregular pentagon that follows the shape of the hilltop, with three vertices (southwest, northwest and northeast) reinforced with towers.

The entrance to the Upper Town was located probably northwest of the tower, on the side from which the fort was the easiest to approach, since it shows the remains of the access ramp.

It is positioned in the Karadak Mountains, at 567 meters above sea level, on the foothills of which Morava e Binçes river flows.

The castle has an interior area of 1.2 hectares and is typical for the Justinian era (6th century), respectively part of the network of fortresses raised in Dardania by the end of late antiquity.

The oldest coin found in the castle dates back to 246–249 and holds the portrait of Otacila Severa, the first wife of Philip.
