In some recent (2002) sources states that the settlement below the fort called Kotorište, which was never fit the actual situation, because Kotorište, the Kotor Varoš's settlement is on the opposite (right) bank of the Vrbanja river. In its original form (whose ruins still exist), there was a tower, slightly up the ridge above the Jakotina river, and dungeon (just above the waterfall). The tower and the dungeons were connected with stone staircase, whose broken remains are still visible. In the tower, until the liberation of Kotor Varoš in 1945, a bell of impressive size  existed. Its fate is unknown. For the first time Kotor was mentioned in 1382. It belonged to Duke Hrvoje Vukčić Hrvatinić (1350-1416). Kotor remained Hrvoje's favourite estate, where he died. Kotor later became part of the Jajce Banovina, and the Ottomans conquered it in 1519, 52 years after the official fall of Bosnia.
