The Quoyness chambered cairn is located on Sanday in Orkney. It is approximately 5,000 years old and is located on the shoreside.
The cairn is about 4 metres high and can be accessed by crawling through the entrance passage, itself 9 metres long. Only half the entrance passage is roofed. A stone platform surrounds the cairn, and when originally built the cairn would have looked like Maeshowe today. Bones from 10 adults and 5 children were removed. The property is now in the care of Historic Scotland.References:
La Hougue Bie is a Neolithic ritual site which was in use around 3500 BC. Hougue is a Jèrriais/Norman language word meaning a \'mound\' and comes from the Old Norse word haugr. The site consists of 18.6m long passage chamber covered by a 12.2m high mound. The site was first excavated in 1925 by the Société Jersiaise. Fragments of twenty vase supports were found along with the scattered remains of at least eight individuals. Gravegoods, mostly pottery, were also present. At some time in the past, the site had evidently been entered and ransacked.
In Western Europe, it is one of the largest and best preserved passage graves and the most impressive and best preserved monument of Armorican Passage Grave group. Although they are termed \'passage graves\', they were ceremonial sites, whose function was more similar to churches or cathedrals, where burials were incidental.
