First built in 1248 as a Romanesque basilica with a nave and two aisles, the cathedral gained its current appearance in the 15th century as a Gothic structure, though the Baroque chapels date from the 16th and 18th centuries. Inside, one is treated to the sight of a lavishly adorned altar, which lights up the place all on its own.
The 57 metre high classicist designed bell tower dates back to the end of the 18th century as the primarily 76-metre high bell tower built by Pavel Porta in the year 1623 was struck by lightening.
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.
