Ale's Stones (Ales stenar) is a megalithic monument which consists of a stone ship 67 meters long formed by 59 large boulders of sandstone, weighing up to 1.8 tonnes each. According to Scanian folklore, a legendary king called King Ale lies buried there.
The carbon-14 dating system for organic remains has provided seven results at the site. One indicates that the material is around 5,500 years old whereas the remaining six indicate a date about 1,400 years ago. The latter is considered to be the most likely time for Ales Stenar to have been created. That would place its creation towards the end of the Nordic Iron Age.
In 1989, during the first archaeological excavations performed in order to scientifically investigate and date the monument, archaeologists found a decorated clay pot with burned human bones inside the ship setting. The bones are thought to come from a pyre and to have been placed in the pot at a later date. The pot's contents varied in age; some material was from 330-540 CE while a piece of charred food crust also found inside was determined to be from 540-650 CE. The archaeologists working on the project also found birch charcoal remains from 540-650 CE underneath an undisturbed boulder. According to the Swedish National Heritage Board, carbon-14 dating of the organic material from the site indicates that six of the samples are from around 600 CE, while one sample is from ca. 3500 BCE. The diverging sample came from soot-covered stones that are believed to be the remnants of an older hearth, found close to the ship setting. On the basis of these results, the Swedish National Heritage Board has set a suggested date of creation for Ales Stenar to 1,400 BP, which is the year 600 CE.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.
