The Castello di Naro was built on top of a hill in the 14th century by the Chiaramonte family. The complex includes walls with battlements, a square tower built by Frederick II of Aragon and the imposing 'mass of the male'. On the east side there are two mullioned Gothic windows that illuminate the great 'Hall of the Prince', which is located on the first floor of the tower. The portal is flanked by two rectangular bastions. The massive outer walls are interspersed with two cylindrical towers and two square towers.
Inside the walls there is a large courtyard, which housed the accommodation of the garrison, the chapel and the stables, and in the case of attack offered refuge to local farmers.
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.
