Starý zámok (literally Old Castle) is well preserved castle complex built in the 15th and 16th centuries. It was embedded to the church of Our Lady from the 13th century. The first documented mention dates from 1486. The church was damaged by earthquake in 1443 and the reconstruction to the fortress was made between 1495-1515 against the Turkish threat. The last significant restoration on the defense complex was carried out in 1777.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.
