Cales Coves is an emblematic and spectacular prehistoric necropolis, both for its setting and for the large number of tombs in it. They take the form of a set of cavities excavated from the rock walls of the ravines and coastal cliff faces (about 90 altogether), used by local communities to bury their dead. Several types of cave have been documented. The necropolis was used for about 1000 years, from the 11th century BCE up until the Romans took control.
In the Roman era, despite no longer being in use as a necropolis, a series of inscriptions on the cave walls testify to their use as a place of pilgrimage, as can be seen in the famous Cova deis Jurats. Calescoves was also a major anchorage port, especially between the 4th century B.C. and the 6th century A.D., with ships arriving from powerful trading nations along the Mediterranean coast.
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.
