The fort is located on the hill of Kosmač, close to the village of Brajići on the Budva-Cetinje road, at an altitude of about 800 meters above sea level. It was constructed using finely-dressed limestone obtained from local quarries. The fort was built on a roughly north–south alignment and consists of a symmetrical building with two wings meeting a central semi-circular section at an angle of about 20 degrees. The end of each wing has a semi-circular extension that faces east at a right angle to the main line of the wing. This design gave the fort's defenders views in eight directions, with rectangular windows and large arched gun ports facing out over the hinterland. The central semicircular tower faces west and seaward.
The fort is now in a ruinous condition and it continues to be neglected and its disintegration is still ongoing.
It once had three storeys, but the topmost storey has collapsed entirely, leaving it roofless. The interior walls, floors and central staircase have also collapsed. Although the remains of the main staircase are still visible, the steps have disappeared entirely and the upper level cannot be reached, though there is nothing left of the upper floor to stand on in any case.
The interior of the fort is strewn with large quantities of fallen masonry, completely obscuring the original floor level. The extent of the collapse is so complete that it is no longer known how the interior was originally laid out. There are substantial holes in the interior's vaulted ceiling. The exterior has been subjected to some stone-robbing in pursuit of the finely-worked square blocks of grey limestone that were used to line the fort's outer walls.
