Bočac Fortress is located on the left bank of the Vrbas River, on the half of motorway E661, between Banja Luka and Jajce. It was built in the early 15th century on a rock, in order to defend the crossing over the Vrbas River. The Fortress was mentioned for the first time in a charter from 1448. From 1463 to 1527, when it fell under the Ottoman rule, the city used to be the fortification of the Banovina of Jajce. In the early eighteenth century, Bočac was mentioned as a settlement with a few cannons. It was abandoned before 1833. During the Ottoman occupation it was subsequently fortified and maintained and the fortified walls and towers that surround the large garden of the town are relatively well preserved today.
References:The Broch of Gurness is an Iron Age broch village. Settlement here began sometime between 500 and 200 BC. At the centre of the settlement is a stone tower or broch, which once probably reached a height of around 10 metres. Its interior is divided into sections by upright slabs. The tower features two skins of drystone walls, with stone-floored galleries in between. These are accessed by steps. Stone ledges suggest that there was once an upper storey with a timber floor. The roof would have been thatched, surrounded by a wall walk linked by stairs to the ground floor. The broch features two hearths and a subterranean stone cistern with steps leading down into it. It is thought to have some religious significance, relating to an Iron Age cult of the underground.
The remains of the central tower are up to 3.6 metres high, and the stone walls are up to 4.1 metres thick.
