The first stone castle in Alsunga was built in 1372, starting with the central part of the southern wing. The authorised representative of the Livonian Order, who was subject to a higher-ranking official in Kuldīga, lived here. The guard towers and other parts of the castle were gradually added between the 15th and the 18th century. The Baroque castle with its two towers is quite impressive. Institutions in the building are the Alsunga Administrative District Council, a museum, a tourist information centre, and others.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.
