Encinas Castle is dated back to the 14th century. The castle consists of a small and square enclosure, with two square towers in two of its corners. One of these served as the keep. In the other two corners the crenelated walls are raised to the same height as the two towers thus giving the false impression that the castle had four towers. There is a small stone ditch at the feet of the walls, which is provided with a low defensive wall.
In the 1950's the ruined castle was acquired by the Ministry of Agriculture. They restored it and turned it into a cereal silo. During these restorations however they blinded original windows and totally destroyed its medieval interior.
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.
