Trollenäs Castle is known since the 14th century, and has been in the ownership of only two families, Thott and Trolle. Originally known as Näs Castle, it was renamed after Trolle family in the 18th century. The current building goes back to 1559 and was in the late 19th century renovated by architect Ferdinand Meldahl to resemble a French Renaissance castle.
There is also a medieval church, Näs old church, near the castle. The castle is open to the public, offering facilities for weddings, conferences, dinners, and other festivities. In the park there is a café.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.
